The first of four new roundabouts for the Lincoln Eastern Bypass is now open to motorists.
The B1188 Lincoln Road, Branston, roundabout is substantially complete and open to motorists, but final surfacing works will need to be undertaken later in the project.
Additionally, works are still required on the splitter islands, street lighting, signage and lining.
Over the next three months Lincolnshire County Council will be working on the new roundabouts at Sleaford Road and Greetwell Road. They will also continue the construction of the new River Witham viaduct and the bridge at Heighington Road.
The county council said it is on track to open the new bypass, which was originally delayed from December 2019, next Spring.
Councillor Richard Davies, executive member for highways, said: “Following three full months of weekend road closures at Lincoln Road, the first of the bypass roundabouts is now officially open.
“This is a huge milestone for the project because it means people can now drive along an actual section of the new road.
“Things are continuing to progress smoothly, and we are on track to open the new bypass next Spring, making it quicker and easier for people in and around the city to get around.”
The Lincoln Eastern Bypass project, which is part-funded by a £50 million Central Government capital grant, recently reached its halfway point and a series of road closures will be ramped up in the coming months.
