The Project

The A1 Trunk Road is a north-south regional route of strategic importance connecting the two sections of the A1(M) at Peterborough in the south and Blyth in the north. Most of this length is of a satisfactory standard but there are localised problems at six roundabouts.

The Highways Agency proposes to replace the following single level roundabouts with grade separated junctions to reduce congestion, queuing and delays in these areas and to improve a poor safety record:

  • Blyth (A1/A614)
  • Apleyhead (A1/A614/A57)
  • Markham Moor (A1/A57)
  • Gonerby Moor (A1/B1174)
  • Colsterworth (A1/A151) and the junction of A1/B6403
  • Carpenters Lodge (A1/B1081)

For further information about the proposals, see the document Summary of Proposals, which you can find on the right hand document menu.

Diversion routes are in place for B6403 traffic. Northbound A1/B6403 traffic is diverted to Grantham South junction (A1/A607/A52) to turn and return down the A1 southbound to the B6403. Southbound A1/B6403 traffic is diverted to Colsterworth South (A1/A151/B676) roundabout.

The bridge deck at Colsterworth South A1/A151 junction was moved and lifted into place on Saturday 17th May and Sunday 18th May. The Colsterworth North   A1/B6403 junction bridge deck was moved and lifted into position on Saturday 19th and Sunday 20th July.

Further details of the works and traffic management can be found at the Colsterworth Site Compound near Colsterworth.
