A1(M)

Improvement work to the existing A1 and A1(M) between its junctions with the M18 and M62 in West Yorkshire. The full, official title of this scheme is "A1 M18 to M62 Redhouse to Darrington and Doncaster bypass", which reflects the fact that this work was previously being pursued as two separate projects, one to widen the Doncaster Bypass and the other to upgrade the A1 between Redhouse and Darrington.

Upgrade of the A1(M) motorway between junction 6 (Welwyn Garden City) and junction 8 (Stevenage north) to Smart Motorway. The hard shoulder will be converted into a permanent running lane to provide three lanes in both directions for the whole of this length of motorway, a communications upgrade will be carried out and variable speed limits installed.

Upgrade of the existing dual carriageway A1 between Leeming Bar and Barton to a dual three-lane motorway. This scheme will remove the last remaining all-purpose section of A1 between West Yorkshire and Gateshead, and will finally connect the north-east conurbation of Newcastle, Gateshead and Sunderland to the national motorway network.

Upgrade of the existing two-lane all purpose dual carriageway A1 to three-lane motorway standard, from Dishforth (the northern terminus of the North Yorkshire motorway) to Leeming Bar, approximately half-way to the next motorway section at Barton.

The original intention, to upgrade the whole section from Dishforth to Barton in one scheme, was replaced with two separate schemes to be completed one after the other. The Leeming to Barton scheme was then dropped due to government spending cuts.

Upgrade of the existing dual three-lane all-purpose dual carriageway A1 to dual three-lane motorway standard, linking the motorway sections at Bramham and Wetherby. The works will involve closing the junctions at Bramham and south of Wetherby. Many local residents are unhappy with the plans as they will put all traffic between the A1 and A58 onto the narrow A659, which is widely thought to be unsuitable. The works will also provide a single-carriageway all-purpose road on the inside of the new Wetherby Bypass motorway to cater for local traffic.

Upgrade of existing two-lane all purpose dual carriageway A1 to three-lane motorway standard, from Darrington (south of M62) to Hook Moor (M1). This is part of the Highways Agency's strategy to upgrade the A1(M) from Doncaster to Barton. The new dual three-lane road will be created off-line and the original A1 narrowed.

Upgrade of existing two-lane all purpose A1 to three-lane motorway standard, from B1224 (part-way along the Wetherby Bypass) to Walshford (the southern terminus of the next section of motorway). This is part of the Highways Agency's strategy to upgrade the A1(M) from Darrington to Barton.
