East - Maintenance schemes

Following an incident on 1 November 2024, a culvert carrying the A1 over Billing Brook near Water Newton was badly damaged by a large vehicle.

The structure supporting the A1 southbound embankment has suffered significant damage, which means that we’ve had to close one lane on the A1 between Stibbington to Water Newton in Cambridgeshire to all vehicles for safety. 

We have been investigating during nighttime shifts. As a result, we’ve been looking at a range of repair options, and doing everything we can with minimum disruption to the A1 whenever possible.

We also need to consider archaeological aspects due to a nearby roman town which is a Historic England protected area, and environmental concerns due to a Site of Special Scientific Interest close by.

We plan to do repair work this Summer. In the meantime, one lane will remain closed, with a 50mph speed limit in place.
