Cllr Richard Davies, executive member for highways, said: “These upcoming A1 closures will allow Galliford Try a safe timeframe to carry out additional drainage, street-lighting, verge and final bridge joint works on the A1 near Grantham as part of our ongoing relief road project.

“Each of these will no doubt cause some disruption, particularly the weekend closure starting Friday 20 May, so we encourage people to plan accordingly and leave extra time for their journeys.

"Despite the second phase of the relief road project being all but complete, we won’t be opening the A1 new connection until a bit further down the line.

"This will not only ensure the safety of those working at the Tollemache Road site compound, but will also allow National Highways time to complete all their checks and for the site team to complete any required final works.

"In the meantime, phase three is progressing ahead really well, and we're still on track for having the entire relief road opened in 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.
