Interstate 93 (I-93) is an Interstate Highway in the New England region of the United States. It begins in Canton, Massachusetts, in the Boston metropolitan area, at I-95; and ends near St. Johnsbury, Vermont, at I-91. It is one of three mainline Interstate highways located wholly within New England, the other two being I-89 and I-91. The largest cities along its route are Manchester, New Hampshire and Boston, Massachusetts. It also passes through the New Hampshire state capital of Concord.
For most of its length, I-93 indirectly parallels U.S. Route 3. Particularly in New Hampshire, the two highways have several interchanges with each other, as well as a concurrency through Franconia Notch State Park. I-93 follows the Southeast Expressway south of downtown Boston, the Central Artery through Boston, and the Northern Expressway from Boston to the New Hampshire state line.

Interstate 93's southern terminus is at exit 12 of I-95 in Canton, co-signed with U.S. Route 1 North. At this junction, I-95 North heads to the northwest (co-signed with U.S. Route 1 South, as well as Route 128, which begins at the interchange), to serve as the beltway around Boston, while I-95 South runs by itself southwest through Boston's southwestern suburbs toward Rhode Island. This violates the numbering plan for the highway system of the United States, which dictates that the signed number for odd-numbered interstates increase from west to east, and therefore I-95 should be farther east than I-93.
The southernmost 3 miles (4.8 km) of I-93 run east through Boston's southern suburbs, passing through Canton and Randolph. In Randolph, I-93 meets the northern end of Route 24 (Fall River Expressway/AMVETS Memorial Highway) at Exit 4. I-93 continues east into Braintree, interchanging with Route 3, the major freeway linking Boston to Cape Cod, at Exit 7 (known locally as the "Braintree Split"). Route 3 North joins I-93 and US-1, and the highway turns north toward Boston. These first 7 miles (11 km) of I-93 follows what was formerly part of Massachusetts Route 128 before it was truncated at the current I-95/I-93 junction and many locals still refer to this section of roadway as part of Route 128.
Upon turning northward, the highway is known as the Southeast Expressway passing through Quincy and Milton before crossing into the city of Boston over the Neponset River. After the Massachusetts Avenue connector exit, the highway officially becomes the John F. Fitzgerald Expressway, which is also known as the Central Artery, and passes beneath downtown Boston. A major intersection with the Massachusetts Turnpike/Interstate 90 (Exit 20) takes place just south of downtown Boston. After the massive interchange, motorists use the Thomas P. O'Neill Jr. Tunnel to travel underneath the city and then use Zakim Bunker Hill Bridge to cross the Charles River. Two exits are located in the tunnel, where the speed limit is 45 miles (72 km) an hour. Route 3 leaves the Artery just before the Zakim bridge via Exit 26, and U.S. Route 1 leaves the Artery just after the bridge, via Exit 27 (no southbound access). From Boston through the rest of Massachusetts, Concord, NH appears as the control city on northbound overhead signs. The Artery ends as I-93 continues north out of the city.
I-93 continues through the northern suburbs of Boston, coming in Woburn to a second intersection with Interstate 95 and Route 128, which run in a concurrency. Travelers going north can either change over to I-95 north to eventually reach Maine, or remain on I-93 toward New Hampshire. Farther north, in Andover, I-93 meets I-495, providing access to Worcester to the southwest and New Hampshire's seacoast region to the northeast. Just south of the state line, I-93 crosses the Merrimack River into Methuen, where it interchanges with Routes 110 and 113 at exit 46 just north of the river crossing. Prior to August 2016, the Route 110 and 113 junction beneath I-93 was a rotary, but current construction routes the highways straight under I-93. While two new ramps are being built at the interchange to complete the new partial cloverleaf format, there are temporary signals and inlets at the end of two existing ramps to serve traffic that will soon be using the new loop ramps. Work began in July 2014 on the project, and with the rotary now closed, demolition of the rotary will be underway in late 2016. The full project is scheduled for completion in June 2018. I-93 then interchanges with the western end of Route 213, a connector between I-93 and I-495. I-93 then crosses into New Hampshire after about 1 mile (1.6 km).
In all, I-93 has 48 numbered exits in Massachusetts, although several numbers are skipped in and near Boston. One noteworthy reason that some exits were removed from I-93 is to further address traffic problems in addition to converting the Central Artery from six to eight to ten lanes, by reducing the combined number of on- and off-ramps from 27 to 14. Exit 48 in Methuen, just before the New Hampshire state line, is the highest-numbered exit along the entire route. I-93 once had only 22 exits prior to the re-routing of I-95 onto MA 128. Due to the highway being one of the two major Interstates that enter Boston directly (Interstate 90 is the other), nearly the entire length of the highway in Massachusetts carries four lanes in each direction. Average daily traffic volumes on I-93 in the state range from 100,000 vehicles at the New Hampshire border and 150,000 vehicles at the southern end at I-95 to over 200,000 vehicles through Braintree and Quincy.
Interstate 93 travels just over 131 miles (211 km) in the Granite State, around two-thirds of the highway's total distance. Serving as the main interstate route in New Hampshire, it connects the state capital, Concord, and its largest city, Manchester. Beyond Concord are the towns of Tilton, Plymouth, and Littleton. I-93 is designated as the Alan B. Shepard Highway, from the Massachusetts line to Hooksett (just north of Manchester at the northern terminus of I-293), as the F.E. Everett Turnpike from Hooksett to Concord, and as the Styles Bridges Highway from Concord to the Vermont line. This section of roadway was constructed between 1961 and 1977.
Between the northern end of I-293 in Hooksett and the beginning of I-89 in Bow, I-93 also carries the northern end of the Everett Turnpike. There is one toll booth along this section, at Exit 11 in Hooksett; toll for passenger cars is $1 (50¢ at the ramp toll booth). This is the only toll collected along the entire length of Interstate 93. I-93 in New Hampshire is also notable for having state liquor stores serve as rest areas, which are passed just after the toll plaza, traveling north. There are separate stores on both sides of the Interstate for travelers in each direction.
I-93 enters New Hampshire at Salem. A rest area/welcome center is available on the northbound side of the freeway, directly before Exit 1. I-93 remains three lanes wide in each direction for its first 7 miles (11 km), until after the exit 3 interchange in Windham. It then drops to two lanes until the split with Interstate 293 and the junction with New Hampshire Route 101 add a third and fourth lane back to the freeway. I-93 and New Hampshire Route 101 run concurrently for about 1 mile (1.6 km) before New Hampshire Route 101 heads directly east as its own freeway, serving Portsmouth and the Seacoast region. I-93 keeps three lanes of traffic in each direction until the junction with Interstate 89, when each side reduces back to two, and remains a four-lane freeway through most of its journey northward, with the only exception being the Franconia Notch section.
It crosses the Merrimack River again before going through the state capital of Concord. In Concord, Interstate 393 heads directly east (co-signed with eastbound U.S. Route 4 and U.S. Route 202), providing another route to the Seacoast region. Westbound U.S. Route 4 joins I-93 and runs concurrently with it until Exit 17 for Penacook, about 5 miles (8.0 km) further north, before exiting westward. Continuing north, I-93 traverses the Lake Winnipesaukee tourist region and makes its way north through the heart of the White Mountains Region. I-93 passes through Franconia Notch State Park as a Super-2 parkway (one lane in each direction) with a 45 miles per hour (70 km/h) speed limit, designed to reduce I-93's impact on Franconia Notch. For the trip through Franconia Notch, I-93 and U.S. Route 3 run concurrently.
Beyond Franconia Notch State Park, U.S. 3 heads northeastward through the Great North Woods region, while I-93 runs to the northwest. The final town along I-93 in New Hampshire is Littleton, served by four exits. Many motorist services are available at Exit 42. After passing through town, it crosses the Connecticut River into Vermont. The last exit along I-93 is exit 44 for Monroe, through which a rest area/welcome center is accessible to travelers on both sides of the highway.
In 2013, a bill was signed by governor Maggie Hassan to raise the speed limit on Interstate 93 to 70 mph (115 km/h) from mile marker 45 to the Vermont border. The new limit took effect on January 1, 2014.
Interstate 93 runs for 11 miles (18 km) in Vermont, with one numbered exit in the state before ending at the interchange with Interstate 91 in St. Johnsbury in the Northeast Kingdom of Vermont. A rest area/welcome center is located along the northbound side of the highway for travelers entering from New Hampshire. The final 3 miles (4.8 km) of the Interstate, just before its terminus, actually veer to the southwest. Vehicles bound for Canada can use northbound I-91 to reach the Derby Line/Stanstead border crossing at that Interstate's end, and northwards into Canada as an "autoroute" freeway into the Canadian province of Quebec. The portion of I-93 in Vermont parallels both U.S. Route 2 and Vermont Route 18.
The Southeast Expressway was constructed between 1954 and 1959, at the same time the John F. Fitzgerald Expressway (Central Artery) was built. Its northern terminus is at Exit 18 (Massachusetts Avenue) in South Boston, a former Y-interchange where the cancelled Inner Belt (I-695) was to meet with the expressway and the Central Artery. The southern terminus is at the Y-interchange (the "Braintree Split") at Exit 7 in Braintree (the former southern terminus of Route 128). A section of the Expressway, beginning south of the Savin Hill overpass and ending just before the Braintree Split utilizes a zipper lane, in which a movable barrier carves out a reversible high occupancy vehicle lane on the non-peak side of the highway during rush hour. Most of the right of way for the Granite Railway in Milton and Quincy was incorporated into the expressway.
The Central Artery, officially the John F. Fitzgerald Expressway, was a section of highway in downtown Boston constructed in the 1950s and was originally designed as a fully elevated highway. This new highway was greatly disliked by the citizens of the city because it cut the heart of the city in half, cast long, dreary shadows and was an eyesore to the community. Because of the public outcry, Gov. John Volpe ordered the southern half of the highway redesigned so that it was underground; this section became known as the Dewey Square Tunnel. With the cancellation of the highway projects leading into the city in 1972 by Gov. Francis W. Sargent, the Central Artery gained the designation of Interstate 93 in 1974. It has also carried the local highway designations of U.S. 1 (since 1989) and Route 3.
By the mid-1970s, I-93 had outgrown its capacity and had begun to deteriorate due a lack of maintenance. State Transportation Secretary Frederick P. Salvucci, aware of the issues surrounding the elevated roadway, proposed a plan conceived in the early 1970s by the Boston Transportation Planning Review to replace the rusting elevated six-lane Central Artery with a new, more efficient underground roadway. This plan was merged with a long-standing proposal to build a third harbor tunnel to alleviate congestion in the Sumner and Callahan tunnels to East Boston; the new plan became known as the Central Artery/Tunnel Project or the Big Dig.
These new roadways were built during a twelve-year period from 1994 to early 2006. The massive project became the largest urban construction project ever undertaken in American history. Construction on the new I-93 segment was not without serious issues: a lengthy Federal environmental review pushed the start of construction back from approximately 1990, causing many inflationary increases; funding for the project was the subject of several political battles between Pres. Ronald Reagan and Rep. Thomas P. O'Neill, Jr. Major construction on the new roadway was done while maintaining the old roadway, a step that also greatly increased the cost of the project. The original Charles River crossing, named Scheme Z, was the object to great public outcry similar to that of the building of the original highway. The outcry eventually led to the replacement of Scheme Z with a newer, more sleek cable-stayed bridge and complementing exit for Cambridge, increasing the cost even more.
In Downtown Boston, I-93 is now made up of the Thomas P. O'Neill Jr. Tunnel and the Zakim Bunker Hill Bridge, which spans the Charles River. The underground construction of the tunnel system was completed as of October 2006; however, repairs continue to many parts of the tunnel due to water leakage because of improper construction of the slurry walls supporting the O'Neill tunnel. The former route of the above-ground Artery, so named "the other Green Monster" by Mayor Thomas Menino, was replaced mostly by open space known formally as the Rose Kennedy Greenway.
Additional improvements were done in the South Bay section of the highway: The I-90/I-93 interchange was completely redesigned, a new HOV lane extending from the zipper lane in Quincy was added and the South Boston Haul road that was constructed to bypass truck traffic around residential streets in the South End is now open to general traffic.
Hazardous cargoes are now prohibited from I-93 in Boston due to safety issues in the tunnels; these cargoes must now exit at either the Leverett Circle connector in Cambridge when traveling southbound or at the Massachusetts Ave. exit when traveling northbound.
The Northern Expressway was constructed from Medford to the New Hampshire border between 1956 and 1963. It was extended through Somerville and Charlestown to the Central Artery, U.S. Route 1, and the planned route of the Inner Belt between 1965 and 1973. Because it was already under construction, the highway was granted an exception to the moratorium on highway expansion inside Route 128 which was announced in 1970.
I-93's original southern terminus was in Cambridge (just north of Boston) where it was to meet the Inner Belt (I-695). However, when that route was canceled, and the I-95 section into Boston was canceled and rerouted along Route 128 in the mid-1970s, I-93's route was extended an additional 18 miles (29 km) down the Central Artery (which had been signed as a concurrency of I-95/MA-3 before I-95 was rerouted) and the Southeast Expressway (what was then just Route 3) from Boston to Braintree and then west along former Route 128 to its intersection with I-95 in Canton.
In an attempt to alleviate rush-hour traffic jams, travel in the breakdown lane of I-93 is permitted on a small stretch between Exit 41 and Exit 47/48. This extra travel is permitted on the southbound side on weekdays between 6AM and 10AM, and on the northbound side between 3PM and 7PM. However, on most busy days this fails to prevent traffic delays. The Massachusetts State Police is displeased with this arrangement, citing that traffic in the breakdown lanes interferes with the ability of emergency vehicles to respond to accidents.
In August 2010, in Medford, a 25-by-7-foot (7.6 m × 2.1 m) section of bridge deck on the northbound side partially collapsed due to age-related structural fatigue. The collapse forced the Massachusetts Department of Transportation to evaluate the remaining bridges along the corridor, eventually deciding to replace several bridges along the highway in a plan called 93 Fast 14. MassDOT set in motion a plan to replace the superstructure and concrete decks on 14 overpass bridges along that section of the interstate, using rapid bridge replacement methods. The $98.1 million project replaced bridges originally built in 1957 with a set of prefabricated modular concrete bridges in a series of weekend roadway closures. Traffic was diverted into a series of crossover lanes during construction. The main part of the project took place each weekend from June through August 2011,with the exception of the July 4th holiday weekend. One or two bridges were replaced each weekend during the construction time frame. The project was part of the Commonwealth's Accelerated Bridge Program.
Off exit 46 in Methuen, Massachusetts, the surface level traffic circle is being rebuilt as part of an overall infrastructure improvement that included a new 8-lane bridge for I-93.
Exit 1 in Salem was originally designed and built with ramps allowing northbound traffic to exit to Rockingham Park and return drivers to southbound 93 only. The complementary ramps were added much later, with the southbound off ramp being a particularly tight and dangerous turn squeezed within the curve of the southbound on ramp, which was replaced in August 2012.
A 7.6-mile (12 km) section of I-93 through Franconia Notch State Park, called the Franconia Notch Parkway, was constructed as a two-lane freeway with a median divider. This was built as a compromise between the state's park department and highway officials. The speed limit on the parkway is 45 mph (70 km/h). Originally, this section's signage read "U.S. 3 TO I-93", complete with its own exit number sequence, but this has since been replaced by I-93 and US-3 signage along the entire length of the parkway. The exits were renumbered to Exit 34A, 34B, and 34C. This section of the highway is now the only remaining section of two-lane freeway on an Interstate highway in the United States.
Construction of Interstate 93 was completed in 1982 in Vermont. It was planned to be built longer if I-91 didn't change its designation eastward in northeastern part of the state. It was the last interstate to be built in the state.
Since 1996, MassHighway has studied rebuilding the intersection of I-93 and I-95 in Woburn along the border with Stoneham and Reading. The project was expected to start in Spring 2017 and cost $267 million, however continued community opposition has postponed the project indefinitely. A project to upgrade the I-93/I-95 interchange in Canton is now underway with the final phase, to construct new flyover ramps that will take traffic from I-95 North over I-93 and from I-93 South to I-95 South, due to start in 2018.
An additional proposal around 2010 to upgrade MA Route 24, running southwards from I-93's current Exit 4, to Interstate 195 near Fall River, MA also has been put off due to studies showing the cost of the project being very high.
The Massachusetts Department of Transportation and its predecessor MassHighway have planned on widening I-93 to a uniform four travel lanes in both directions from the current lane drop near Exit 41 in Wilmington to the New Hampshire border since the beginning of the 2000s. The first section of widening will be done as part of the I-93 Tri-Town Interchange Project. The project will construct a new interchange in Wilmington. I-93 will be widened from 3 to 4 lanes in each direction from Exit 41 to I-495, a distance of approximately 5 miles (8 km), as the first phase in widening I-93 from Exit 41 to the New Hampshire state line. Early estimates of the entire project place the cost at $567 million.
Initial plans to widen I-93 to a uniform four travel lanes in both directions from Salem to Manchester beginning in 2008 were put on hold due to a lawsuit designed to force the NH Department of Transportation to update the plans to include other transportation options. Under orders from US District Court, the NHDOT and US Department of Transportation must provide an updated environmental review. The Conservation Law Foundation (CLF) filed a lawsuit in February 2006, hoping to force any expansion plans in the area to include the restoration of commuter rail service between Manchester and Boston. Despite the suit, the Exit 1 interchange construction was allowed to undergo upgrading and expansion; other associated projects related to the widening, chiefly around Exits 3 and 5, were also eventually allowed to proceed. The whole set of projects were eventually allowed to move forward when an agreement between the state and the CLF that removed the group's opposition to construction which does not pose a threat to the environment.
As part of the 2009 stimulus package, New Hampshire was set to receive several million dollars in highway construction funds. One of the projects was the widening of a portion of the highway between the Massachusetts border and Manchester. Bidding was set to begin in February 2009 with construction slated to begin in late 2009 or early 2010. The plans call for the New Hampshire Department of Transportation to widen the southernmost 20 miles (32 km) of I-93 to four lanes in each direction, from the current two. In addition, all five interchanges along this length will be upgraded to accommodate larger amounts of traffic, including replacing many aging bridges. Smaller construction projects at some of the interchanges are already taking place. According to plans filed by the state with US DOT, the project is scheduled to run from 2009 through 2016, with work starting at the Massachusetts line and moving northward to Manchester. The project is designed with an intermodal transit bent; new or improved park and ride facilities deployed at exits 1, 3 and 5 and a widened median strip that is designed to accommodate a planned commuter rail service between Boston and Manchester.
As a way to help defray the costs of the expansion, in early 2010 the NHDOT made a formal request to the Federal Highway Administration to add tolls to I-93 at the Massachusetts-New Hampshire border. The new toll facility was to be located in Salem, New Hampshire, approximately .5 mi (0.80 km) from the state line, and would cost travelers $2 per car. The proposal faced opposition from state legislators in both states who claimed the tolls would cause severe congestion in the area and lead to an economic burden to local residents. Opponents included US senator Scott Brown (R-Massachusetts). The proposal was eventually dropped in favor of issuing new state bonds to pay for expansion. The new policy was laid out by Transportation Commissioner George Campbell after reviewing the proposal and receiving a promise from the MassDOT that it would not be enacting a similar toll on the Massachusetts side of the border.
Plans were announced in 2012 that I-93 would have a new northbound and southbound bridge over Interstate 89 in Bow, New Hampshire. To reduce traffic on the southbound bridge the NHDOT added a third lane to ease congestion. The bridges were completed in 2014.
More plans were announced in 2014 that the Hooksett, New Hampshire rest areas would be rebuilt. The new rest areas would feature a 14 pump Irving gas station, a new New Hampshire liquor and wine outlet, and a few restaurants and shops. The project was completed in 2015.
Exits 17, 19, 21, and 25 in Massachusetts were eliminated as part of the Big Dig. Massachusetts exit numbers were to be changed to those based on I-93 mileposts with a project that was due to start in early 2016, but this project has been indefinitely postponed by MassDOT.

The biggest project on its list, the $31 million widening of Interstate 93 from Salem to Manchester, will be advertised on Feb. 24, Jannelle said.
The Beebe River is a 16.7-mile-long (26.9 km) river located in the White Mountains of New Hampshire in the United States. It is a tributary of the Pemigewasset River, part of the Merrimack River watershed.
The Beebe River begins at Black Mountain Pond on the southern slopes of Sandwich Mountain, a 3,993-foot (1,217 m) summit in the southern White Mountains, in the town of Sandwich. The river drops off the mountain to the south, then turns west to travel through Sandwich Notch, staying in a wooded valley and entering the town of Campton. The valley broadens as the river approaches the village of Campton Hollow, where the river reaches New Hampshire Route 175 and drops over some small waterfalls. The river passes by the old industrial community of Beebe River and reaches the Pemigewasset River next to Interstate 93.Big Dig
The Central Artery/Tunnel Project (CA/T), known unofficially as the Big Dig, was a megaproject in Boston that rerouted the Central Artery of Interstate 93 (I-93), the chief highway through the heart of the city, into the 1.5-mile (2.4 km) Thomas P. O'Neill Jr. Tunnel. The project also included the construction of the Ted Williams Tunnel (extending I-90 to Logan International Airport), the Leonard P. Zakim Bunker Hill Memorial Bridge over the Charles River, and the Rose Kennedy Greenway in the space vacated by the previous I-93 elevated roadway. Initially, the plan was also to include a rail connection between Boston's two major train terminals. Planning began in 1982; the construction work was carried out between 1991 and 2006; and the project concluded on December 31, 2007 when the partnership between the program manager and the Massachusetts Turnpike Authority ended.The Big Dig was the most expensive highway project in the US, and was plagued by cost overruns, delays, leaks, design flaws, charges of poor execution and use of substandard materials, criminal arrests, and one death. The project was originally scheduled to be completed in 1998 at an estimated cost of $2.8 billion (in 1982 dollars, US$6.0 billion adjusted for inflation as of 2006). However, the project was completed in December 2007 at a cost of over $8.08 billion (in 1982 dollars, $14.6 billion adjusted for inflation, meaning a cost overrun of about 190%) as of 2006. The Boston Globe estimated that the project will ultimately cost $22 billion, including interest, and that it would not be paid off until 2038. As a result of a death, leaks, and other design flaws, Bechtel and Parsons Brinckerhoff—the consortium that oversaw the project—agreed to pay $407 million in restitution and several smaller companies agreed to pay a combined sum of approximately $51 million.The Rose Fitzgerald Kennedy Greenway is a roughly 1.5-mile-long (2.4 km) series of parks and public spaces, which were the final part of the Big Dig after Interstate 93 was put underground. The Greenway was named in honor of Kennedy family matriarch Rose Fitzgerald Kennedy, and was officially dedicated on July 26, 2004.Central Artery
The Central Artery (officially the John F. Fitzgerald Expressway) is a section of freeway in downtown Boston, Massachusetts; it is designated as Interstate 93, US 1 and Route 3.
The original Artery, constructed in the 1950s, was named after John F. Fitzgerald; it was partly elevated and partly tunneled. Its reputation for congestion inspired the local nicknames "The Distressway," "the largest parking lot in the world", and "the other Green Monster" (the paint of the highway girders shared the same color as the left field wall at Fenway Park). The Artery was significantly rerouted during a 10-year period from the mid-1990s through the early 2000s as part of the Central Artery/Tunnel Project (the "Big Dig"). The present-day Artery is almost entirely directed through the newly constructed O'Neill Tunnel, while the original Artery was demolished and replaced with the Rose Fitzgerald Kennedy Greenway, named after the daughter of John F. Fitzgerald and the mother of John F. Kennedy.
According to Massachusetts Executive Office of Transportation data, the Central Artery runs from the Massachusetts Avenue Connector just beyond Andrew Square in South Boston north to the split with U.S. Route 1 in Charlestown. Along with the harbor tunnels and the Massachusetts Turnpike (I-90) from Route 128 to East Boston, it is part of the Metropolitan Highway System.East Branch Pemigewasset River
The East Branch of the Pemigewasset River is a 15.8-mile-long (25.4 km) river located in the White Mountains of New Hampshire in the United States. It is a tributary of the Pemigewasset River, part of the Merrimack River watershed.
The East Branch is a longer and larger river than the river that it flows into, but it is named a branch of the main stem because its source lies deep in the Pemigewasset Wilderness of the White Mountains, while the main Pemigewasset River flows directly from Franconia Notch, a major pass through the mountains. The East Branch begins in the locality known as Stillwater, in a wide valley north of Mount Carrigain and Mount Hancock, where several large brooks converge. The river flows west and southwest through the heart of the Pemigewasset Wilderness, picking up tributaries such as the North Fork of the Pemigewasset and Franconia Branch before reaching, at the Lincoln Woods Visitor Center, the Kancamagus Highway stretch of New Hampshire Route 112.
Now into developed areas, the East Branch meets the Hancock Branch coming from the southeast and flows past the Loon Mountain ski area to the village of Lincoln, New Hampshire. The river crosses into Woodstock and ends at the Pemigewasset River just downstream from the Interstate 93 highway bridges.Echo Lake (Franconia Notch)
Echo Lake is a 38.2-acre (15.5 ha) water body located in Franconia Notch in the White Mountains of New Hampshire, at the foot of Cannon Mountain. The lake is in the Connecticut River watershed, near the height of land in Franconia Notch; water from the lake's outlet flows north via Lafayette Brook to the Gale River, then the Ammonoosuc River, and finally the Connecticut River to Long Island Sound, an arm of the Atlantic Ocean.
Echo Lake lies in Franconia Notch State Park. The park's Cannon Mountain ski slopes rise directly to the southwest of the lake. Interstate 93 (the Franconia Notch Parkway) runs along the lake's eastern shore, and New Hampshire Route 18 passes the lake's northern shore, where a state park swimming beach is located. Artists Bluff, a hill with open ledges, rises north of the lake and provides views south over the lake into the center of Franconia Notch.
The lake is classified as a coldwater fishery, with observed species including brook trout.Franconia Notch
Franconia Notch (elev. 1,950 feet/590 m) is a major mountain pass through the White Mountains of New Hampshire. Dominated by Cannon Mountain to the west and Mount Lafayette to the east, it lies principally within Franconia Notch State Park and is traversed by the Franconia Notch Parkway (Interstate 93 and U.S. Route 3). The parkway required a special act of Congress to sidestep design standards for the Interstate highway system because it is only one lane in each direction.The notch was home to the Old Man of the Mountain, a rock formation which collapsed in 2003 but whose profile remains a symbol of the state of New Hampshire.
The notch is located primarily in the town of Franconia but extends south into Lincoln. It is bordered to the east by Franconia Ridge, comprising Mount Lafayette (5,249 feet/1,600 m), Mount Lincoln (5,089 feet/1,551 m), and Little Haystack Mountain (4,780 feet/1,460 m), and to the west by 4,080-foot (1,240 m) Cannon Mountain and the sheer face of Cannon Cliff. The notch's height of land is located near its northern end, at the base of Cannon Mountain. Echo Lake lies just north of the high point of the notch, with an outlet that flows into Lafayette Brook, then the Gale River, the Ammonoosuc River, and finally the Connecticut River, which enters Long Island Sound at Old Saybrook, Connecticut. Just south of the height of land, Profile Lake lies beneath the cliff that once held the Old Man of the Mountain. Profile Lake is the source of the Pemigewasset River, the primary tributary of the Merrimack River, which flows to the Gulf of Maine at Newburyport, Massachusetts.Haggetts Pond
Haggetts Pond is the reservoir for the town of Andover, Massachusetts, United States. It is located in the western part of the town and also lends its name to a road. The Merrimack River is connected to the pond to add volume to the reservoir.
It is bordered by Route 133 on the south. Not far to the northwest is Interstate 495; to the northeast is Interstate 93. Haggetts Pond is located at 42°38′36″N 71°12′18″W.
Permissible activities include walking, hiking, jogging biking and fishing. Only registered rowboats are allowed on the reservoir and fishing must be done from either the shoreline or a rowboat (no hip waders). Canoeing or kayaking, windsurfing, sailing, ice skating and ice fishing are prohibited. Swimming, bathing, wading and pets in the water are also prohibited.
Hiking trails, some converted out of a former railway (the Lowell and Lawrence Railroad), encircle the pond.
The Pond also gives its name to a road (Haggetts Pond Road) that starts to the west of the pond itself. Haggetts Pond Road transverses Route 133, but the vast majority of its length is on the side north of the pond. (Of the 245 houses on Haggetts Pond Road, 240 of them are on the north side.)Interstate 293
Interstate 293 (I-293) is an 11-mile (18 km) long loop surrounding Manchester, New Hampshire, USA roughly shaped like two sides of a triangle. Completing the loop in the northeast (the third side of the triangle) is Interstate 93. The southern portion of the loop shares the road with NH 101 and passes near Manchester-Boston Regional Airport and the Mall of New Hampshire. The western portion of the loop shares the road with the Everett Turnpike, but there are no tolls on this portion of the turnpike.Interstate 393
Interstate 393 (I-393) is a 4.594-mile (7.393 km) east-west freeway spur extending from Interstate 93 at Concord, New Hampshire, to Pembroke, New Hampshire, United States. The primary purpose of the road is to bypass a densely built commercial strip on Route 9 in the eastern part of Concord. Several times a year, I-393 also serves traffic to events at New Hampshire Motor Speedway in Loudon. I-393 runs concurrently with US 4 and US 202 for its entire length.Leonard P. Zakim Bunker Hill Memorial Bridge
The Leonard P. Zakim () Bunker Hill Memorial Bridge (or Zakim Bridge) is a cable-stayed bridge across the Charles River in Boston, Massachusetts. It is a replacement for the Charlestown High Bridge, an older truss bridge constructed in the 1950s. Of ten lanes, using the harp-style system of nearly-parallel cable layout, coupled with the use of "cradles" through each pylon for the cables, the main portion of the Zakim Bridge carries four lanes each way (northbound and southbound) of the Interstate 93 and U.S. Route 1 concurrency between the Thomas P. "Tip" O'Neill Jr. Tunnel and the elevated highway to the north. Two additional lanes are cantilevered outside the cables, which carry northbound traffic from the Sumner Tunnel and North End on-ramp. These lanes merge with the main highway north of the bridge. I-93 heads toward New Hampshire as the "Northern Expressway", and US 1 splits from the Interstate and travels northeast toward Massachusetts' North Shore communities, crossing the Mystic River via the Tobin Bridge.
The bridge and connecting tunnel were built as part of the Big Dig, the largest highway construction project in the United States. The northbound lanes were finished in March 2003, and the southbound lanes in December. The bridge's unique styling quickly became an icon for Boston, often featured in the backdrop of national news channels, to establish location, and included on tourist souvenirs. The bridge is commonly referred to as the "Zakim Bridge" or "Bunker Hill Bridge" by residents of nearby Charlestown.
The Leverett Circle Connector Bridge was constructed in conjunction with the Zakim Bridge, allowing some traffic to bypass it.Mad River (Pemigewasset River tributary)
The Mad River is a 17.9-mile-long (28.8 km) river located in the White Mountains of New Hampshire in the United States. It is a tributary of the Pemigewasset River, part of the Merrimack River watershed.
The Mad River begins at the Greeley Ponds in Mad River Notch, a gap between Mount Osceola to the west and Mount Kancamagus to the east, in the township of Livermore, New Hampshire. The river descends to the south, followed by the Greeley Pond Trail, to the town of Waterville Valley, where the West Branch enters.
After winding through the Waterville Valley Resort community, the Mad River proceeds southwest over continuous boulder-strewn rapids into a corner of the town of Thornton, eventually settling out in Campton Pond in the town of Campton. Passing over a small hydroelectric dam at Campton Upper Village, the river descends over some small waterfalls and enters the floodplain of the Pemigewasset River, which it joins near Interstate 93.
For most of the river's length below Waterville Valley, it is paralleled by New Hampshire Route 49.Massachusetts Route 24
Route 24 is a freeway south of I-93 in southeastern Massachusetts, linking Fall River with the Boston metropolitan area. It begins in the south in Fall River at the border with Tiverton, Rhode Island where it connects with Rhode Island Route 24, and runs north to an interchange with Interstate 93/U.S. Route 1 in Randolph. Route 24 is also known as the Fall River Expressway, and officially as the Amvets Highway. Route 24 has a total of 21 interchanges (including the split at its northern terminus with Interstate 93.)
Route 24 connects many of the major cities of Southeastern Massachusetts with Boston: Brockton, Taunton, Fall River, and New Bedford (via the junction with Route 140).Massachusetts Route 3
Route 3 is a southward continuation of U.S. Route 3, connecting Cambridge, Massachusetts with Cape Cod. All of it, except for the northernmost end in downtown Boston and Cambridge, is a Controlled-access highway.
The section from Boston to Braintree is also marked as Interstate 93 and U.S. Route 1 and is known in downtown Boston as the Central Artery, and south of downtown as the Southeast Expressway. In Braintree, I-93 and US 1 split to follow the Yankee Division Highway to Interstate 95, and Route 3 continues south on its own, as the Pilgrims Highway. This section extends to a junction with U.S. Route 6 in Sagamore, just before the Sagamore Bridge over the Cape Cod Canal where Route 3 originally ended at rotary. Replacement of this rotary with an elevated "flyover" interchange was completed in November 2006.
Because Route 3 and U.S. Route 3 are treated as the same route by the Massachusetts Department of Transportation (MassDOT), mileposts increase continuously from Bourne to the New Hampshire border.O'Neill Tunnel
The Thomas P. "Tip" O'Neill Jr. Tunnel is a highway tunnel built as part of the Big Dig in Boston, Massachusetts. It carries the Central Artery underneath downtown Boston, and is numbered as Interstate 93 (I-93), U.S. Route 1 (US 1), and Route 3. It roughly follows the route of the old elevated Central Artery, though the northbound entrance, at the corner of Kneeland Street and Atlantic Avenue, is somewhat east of the southbound exit (at Kneeland and Albany streets) to allow for a reconfigured interchange with the Massachusetts Turnpike. It runs from the Zakim Bunker Hill Bridge at its north portal—barely 165 feet (50 m) east of the TD Garden sports facility's eastern corner—to Boston's Chinatown at its south portal. The tunnel is named for Tip O'Neill, former Speaker of the United States House of Representatives.Salem, New Hampshire
Salem is a town in Rockingham County, New Hampshire, United States. The population was 28,776 at the 2010 census. Being located on Interstate 93 as the first town in New Hampshire, which lacks any state sales tax, Salem has grown into a commercial hub, anchored by the Mall at Rockingham Park. Other major sites include the Canobie Lake Park, a large amusement park, and America's Stonehenge, a stone structure of disputed origins. It is the former home of Rockingham Park, a horse racetrack. The Sununu political family hails from Salem, including former New Hampshire governor and White House Chief of Staff John H. Sununu, and his sons John E. Sununu, a former U.S. senator, and Chris Sununu, current New Hampshire governor.South Bay, Boston
South Bay is a 10-acre (40,000 m²) site in Boston, Massachusetts between Chinatown and the Leather District. It is roughly bounded by Kneeland Street, Hudson Street, the Massachusetts Turnpike mainline, and the Interstate 93 mainline. Currently owned by the Massachusetts Turnpike Authority (MTA), the area is taken up by a major highway interchange between 90, 93, and local streets. There were originally plans to re-develop the area with a 600-foot tall office tower, but no such project has taken place.Squam River
The Squam River is a 3.6-mile-long (5.8 km) river located in central New Hampshire in the United States. The river is the outlet of Squam Lake, the second-largest lake in New Hampshire, and it is a tributary of the Pemigewasset River, which itself is a tributary of the Merrimack River.
The Squam River first appears as a narrow channel in Holderness, New Hampshire between Squam Lake and Little Squam Lake downstream. The two lakes have the same elevation, due to a dam below the outlet to Little Squam, so the river in Holderness village is not free-flowing. Below Little Squam Lake the river proceeds south for over a mile before reaching the dam which controls the two lakes' water level. Below this point, the river quickly reaches the backwater from a mill dam in the town of Ashland.
In Ashland, the river drops 50 feet (15 m) in 0.2 miles (0.3 km), sufficient to provide hydropower for numerous industries when the town originally grew in the 19th century. Below the center of town, the river wanders southeast under railroad tracks and Interstate 93 and past the Ashland sewage treatment plant before entering the Pemigewasset River.Turkey River (New Hampshire)
The Turkey River is a 6.1-mile-long (9.8 km) stream located in southern New Hampshire in the United States. It is a tributary of the Merrimack River, which flows to the Gulf of Maine.
The source of the Turkey River is the outlet of Little Turkey Pond in Concord, New Hampshire. The river travels southeast through the campus of St. Paul's School, winding through the outskirts of Concord, and entering Bow before joining the Merrimack near the junction of Interstate 93 and Interstate 89. In May 2006 record amounts of rainfall over two days caused the Turkey River to flood the campus of St. Paul's School, forcing the school year to be ended prematurely.Winnisquam Lake
Winnisquam Lake is in Belknap County in the Lakes Region of central New Hampshire, United States, in the communities of Meredith, Laconia, Sanbornton, Belmont, and Tilton. At 4,214 acres (1,705 ha), it is the fourth-largest lake entirely in New Hampshire. The lake is roughly triangular in shape, with the vertexes pointing north, east, and south. The lake lies along the path of the Winnipesaukee River, which enters the lake from its eastern corner and carries water from Lake Winnipesaukee via Paugus Bay and Opechee Bay. The river also flows south out of Winnisquam's southern corner, eventually joining the Merrimack River. The lake extends several miles north from the course of the Winnipesaukee River, which forms the lake's southeastern side, with the northern point being formed by the confluence of several smaller creeks near the village of Meredith Center. The lake has a maximum depth of 170 feet (52 m).The lake is only a few miles from Interstate 93 via Exit 20 for U.S. Route 3 and New Hampshire Route 11. Winnisquam has two basins, a larger northern basin and a smaller southern one, with a bridge carrying Routes 3 and 11 separating them. The village of Winnisquam is at the bridge.
The Abenaki people occupied the Winnisquam and Winnipesaukee area until colonists arrived in the mid-18th century. Winnisquam's surrounding county, Belknap, was founded in 1840 and named after Jeremy Belknap, a Congregational clergyman and prominent historian.Winnisquam Lake is home to many species of fish. Cold water species include rainbow trout, lake trout, landlocked salmon, and whitefish. The warm water species include small- and largemouth bass, pickerel, horned pout, white perch, northern pike, walleye, black crappie, bluegill, and yellow perch. Remote lake and brook trout stocking is common when authorities find it necessary.
