The road starts at the A57 just outside Sheffield City Centre which forms part of the Sheffield Parkway, then runs to the M1 at Junction 33. Beyond the roundabouts it heads west to Rotherham which it passes as the dual carriageway, four-lane Centenary Way, turning north and northeast towards Conisbrough and Doncaster, passing Conisbrough Castle. Between Warmsworth and Balby it meets the A1(M) at Junction 36. From there it heads east to Doncaster, then passing Armthorpe it heads to the M18 at Junction 4 where the road terminates.[1]

Motorway junctions

The A630 has a junction with M1 at Junction 33 at Catcliffe, another with A1(M) at Junction 36 at Warmsworth, and finally at M18 at Junction 4 at Armthorpe where the road terminates.

River Don Navigation

The River Don Navigation was the result of early efforts to make the River Don in South Yorkshire, England, navigable between Fishlake and Sheffield. The Dutch engineer Cornelius Vermuyden had re-routed the mouth of the river in 1626, to improve drainage, and the new works included provision for navigation, but the scheme did not solve the problem of flooding, and the Dutch River was cut in 1635 to link the new channel to Goole. The first Act of Parliament to improve navigation on the river was obtained in 1726, by a group of Cutlers based in Sheffield; the Corporation of Doncaster obtained an Act in the following year for improvements to the lower river. Locks and lock cuts were built, and, by 1751, the river was navigable to Tinsley.

The network was expanded by the opening of the Stainforth and Keadby Canal in 1802, linking to the River Trent, the Dearne and Dove Canal in 1804, linking to Barnsley, and the Sheffield Canal in 1819, which provided better access to Sheffield. All three were bought out by the Don Navigation in the 1840s, after which the canals were owned by a series of railway companies. The Sheffield and South Yorkshire Navigation Company was created in 1889 and eventually succeeded in buying back the canals and the Don Navigation in 1895, but plans for expansion were hampered by a lack of capital. One success was the opening of the New Junction Canal in 1905, jointly funded with the Aire and Calder Navigation.

During the 20th century, there were several plans to upgrade the Don, to handle larger craft. It was eventually upgraded to take 700-tonne barges in 1983, but the scheme was a little too late, as an anticipated rise in commercial traffic did not occur. Most use of the navigation is now by leisure boaters, whose boats are dwarfed by the huge locks. The navigation and river are crossed by a wide variety of bridges, from a medieval bridge complete with a chapel on it, one of only three to have survived in Britain, to a motorway viaduct that pioneered the use of rubber bearings and a new waterproofing system. In between are a number of railway bridges, including two that were built to carry the internal railway system at the Blackburn Meadows sewage treatment plant. The former railway viaduct at Conisbrough now carries cyclists 113 feet (34 m) above the Don, as part of the National Cycle Network.

The final section to Bramwith is known as the River Dun Navigation.

River Rother, South Yorkshire

The River Rother, a waterway in the northern midlands of England, gives its name to the town of Rotherham and to the Rother Valley parliamentary constituency. It rises near Clay Cross in Derbyshire and flows in a generally northwards direction through the centre of Chesterfield, where it feeds the Chesterfield Canal, and on through the Rother Valley Country Park and several districts of Sheffield before joining the River Don at Rotherham in Yorkshire.

From the 1880s, the water quality deteriorated rapidly, as a result of coal mining and its associated communities. The river became unable to sustain life, and by 1974, was the most polluted of the rivers within the River Don catchment. The pollutants came from coking plants, from inefficient sewage treatment plants, and from the manufacture of chemicals. Major investment in upgrading the sewage treatment works took place, and in the treatment of industrial effluent before it was discharged to the river. The closure of the main coking plants has also aided the recovery of the river, and enabled restocking with fish to begin in 1994. By 1996 there was evidence for self-sustaining fish populations, and that the river could support organised angling.

A short section of the river in Chesterfield was once navigable, and may become so again as part of a development project, while there are plans to use the course from Rother Valley Country Park to Rotherham for the Rother Link, which would connect the Chesterfield Canal to the River Don Navigation. The lower river is managed because of flood risk: three regulators can restrict its flow. Their operation normally causes flooding of washlands, rather than of centres of population, which might otherwise be inundated.
