Highways Agency

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.

Construction of the new over-bridge is being progressed within the boundaries of the existing roundabout. The new main A1 carriageway north and south of the junction is under construction and earthworks for slip roads and new roundabouts are being progressed.

Colsterworth

Site clearance works have been completed. Narrow lanes traffic management has been installed and the cross over at the junction between the A1/B6403 junction has been closed. 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.

Carpenters Lodge

Narrow lanes traffic management has been installed and construction works have commenced on site. Access from the A1 to Racecourse Road is closed. Construction of the new bridge deck is being progressed off line in the fields adjacent to the A1.

Other A1 Schemes

Various maintenance works are being completed on the A1 whilst the major works are being carried out at the junctions.
