Drivers warned of big delays as major roadworks project starts on A1 near Doncaster

National Highways Yorkshire has started a programme of essential improvement works in the Darrington area, which will continue into the New Year.

A spokesman said: “Our essential improvement works have started.

“One lane is closed 24/7 in this area and is causing significant delays.

"If you're travelling further afield, please consider using the M18 and M62 to avoid these works.”

The work will see essential maintenance work on the A1 Darrington Interchange bridge.

Work is expected to finish by the end of January 2022, including a break in December to consider seasonal traffic.

A spokesman said: “We will be working during the week Monday to Friday 8am until 5pm under lane closures, except when we need to install traffic management.

“We will close the carriageway on some dates so we can safely set up, change, and take down the traffic management. This will be done overnight between 9pm and 6am. The work is weather dependent; should there be any delay due to adverse weather conditions.”

“To enable us to carry out this work safely, the A1 Darrington Interchange carriageway will be reduced to one single lane in both directions both day and night, except when road closures are in place.

"A 40mph speed limit will be enforced. For customer safety, we need to leave the traffic management and lane closures in place overnight even when we are not working, as sections of the vehicle restraint barrier will have been removed.

"We ask customers to allow additional time for journeys and apologise for any inconvenience this essential work may cause.”
