Wayne County is the most populous county in the U.S. state of Michigan. As of the 2010 census, its population was 1,820,584, making it the 19th-most populous county in the United States. The 2014 Census update listed the county's population at 1,764,804. The county seat is Detroit, the most populous city in Michigan and 18th-most populous city in the United States. The county was founded in 1796 and organized in 1815.
Wayne County was the sixth county in the Northwest Territory, formed 15 August 1796 from portions of territorial Hamilton County, territorial Knox County and unorganized territory. It was named for the American general "Mad Anthony" Wayne. It originally encompassed the entire area of the Lower Peninsula of Michigan, most of the Upper Peninsula, as well as smaller sections that are now part of northern Ohio, Indiana and Illinois. By proclamation of the Territorial Secretary and Acting Governor, Winthrop Sargent, on August 15, 1796, the boundaries of Wayne County were declared to begin at the mouth of the Cuyahoga River then west to Fort Wayne, then to the southernmost point of Lake Michigan and along the western shore north to the territorial boundary in Lake Superior and then along the territorial boundary through Lake Huron, Lake St. Clair, and Lake Erie back to the starting point.
On January 14, 1803, the Governor of Indiana Territory, William Henry Harrison, issued a similar proclamation defining the boundaries as beginning at a point where an east and west line passing through the southernmost extreme of Lake Michigan would intersect a north and south line, passing through the westernmost extreme of the lake, then north to the territorial boundary, then along said boundary line to a point where an east and west line passing through the southerly extreme of Lake Michigan would intersect the same, then along this last mentioned line to the place of beginning. This boundary would include Chicago, Illinois and a sizable strip of Wisconsin along Lake Michigan.
According to the U.S. Census Bureau, the county has a total area of 673 square miles (1,740 km2), of which 612 square miles (1,590 km2) is land and 61 square miles (160 km2) (9.0%) is water. Its water area includes parts of the Detroit River and Lake St. Clair.
The eastern (and sometimes southern) boundary is a water boundary in the Detroit River and Lake St. Clair with Essex County, Ontario. Automotive traffic crosses this boundary at the Detroit-Windsor Tunnel and the Ambassador Bridge. Due to the southwestern course of the river, this small portion of Canada actually lies to the south of Wayne County. The southern communities of the county are usually referred to as "Downriver", in reference to their location downstream of downtown Detroit.
The Wayne County Department of Public Services was formed in 1906 as the Wayne County Road Commission. It was the government agency in Wayne County, Michigan responsible for building and maintaining the county's roads and highways.
The Wayne County Road Commission was an "exemplary" agency in the state of Michigan, and had great involvement and influence in roadway planning more widely in the state. It became "internationally renowned for innovative ideas, sometimes breaking ground well in advance of the Michigan State Highway Department.":32
The county road commission was more advanced than the state's own public works department in several respects. It had long had its own in-house construction group to build bridges, before the state copied that practice in 1924.:10 It adopted one or more bridge types before the state did.
Its first commissioners were Edward N. Hines, Cassius R. Benton, and automobile manufacturer Henry Ford. While the commission was authorized by an 80% positive vote of county voters in a 1906 referendum, it was controversial and there was a Michigan state supreme court case pressed which found it unconstitutional. Commissioners Benton and Ford quit, but commissioner Hines persisted and led the commission through reorganization getting around the obstacles.:33 Hines was a commissioner continuously from 1906 to 1938.
Hines is credited with the idea of putting a painted line down a roadway's center to divide traffic, and other innovations that were later widely adopted.
The commission worked systematically, and it became a model to others. "As early as 1911, the commission felt confident in asserting that 'Wayne County is coming to be known as a leader in the good roads movement, and the Mecca of those upon whose shoulders devolves the duty of solving traffic problems.' Within a few years, the county hosted delegations of engineers from around the United States, as well as from a number of other countries, including Britain, Japan, Australia, and Borneo.[footnote omitted] The commission's international prominence was enhanced by its advocacy of concrete as a road material. It claimed credit for constructing the country's first mile of concrete-paved rural highway, a section of Woodward Avenue" just outside the Detroit city limits.
The county road commission led in calling, during the 1930s, for superhighways in the state to relieve congestion; it worked to build superhighways in conjunction with the state plan that emerged, and which the county road commission endorsed.
The state relied upon the Wayne County Road Commission to provide expertise to build the Willow Run Expressway, during World War II as many state staff went into military service.:18 The state hired the county road commission to supervise the building of the Lodge Expressway.:27

Wayne County is Michigan's first "charter county", with a home rule charter setting up its structures within limits set in state law and constitution. Most Michigan county governments are structured according to state law, without a locally adopted charter. The city is governed pursuant to the Home Rule Charter of Wayne County, Michigan, and the Wayne County Code is the codification of Wayne County's local ordinances. Unless a violation of the code or other ordinance is specifically designated as a municipal civil infraction (or unless expressly otherwise required by applicable state or federal laws), the violation is a misdemeanor.
The county government operates the jail, maintains rural roads, keeps files of deeds and mortgages, maintains vital records for all areas except Detroit, administers public health regulations, and participates with the state in the provision of welfare and other social services. Most other local government functions – police and fire, building and zoning, tax assessment, street maintenance, etc. – are the responsibility of individual cities and townships.
