The diversion route for the northbound A1 closures will be via the B1174 at Little Ponton through Grantham to Gonerby Moor.

The diversion route for the southbound A1 closures will be via the B1174 at Gonerby Moor through Grantham to Little Ponton.

Councillor Richard Davies, executive member for highways, said: "These closures will allow Galliford Try to safely carry out essential works to the A1 as part of the Grantham Southern Relief Road project.

"The second phase of the scheme, which connects the A1 to the B1174, is set to be finished this autumn.

"Meanwhile, construction of the third, and final, section of Grantham's new relief road is underway now, with the team focusing on earthworks and drainage works ahead of building the new River Witham bridge and tying the road into the A52 at Somerby Hill.

"As a whole, this massive project is coming along well and we're still on track for having the whole relief road opened by the end of 2023."

The Grantham Southern Relief Road project is being led by Lincolnshire County Council and supported by South Kesteven District Council, Greater Lincolnshire LEP, Highways England, Department for Transport, Network Rail, Homes England and local businesses.
