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.

We’re upgrading our street lighting to LED between junctions 32a and 32b.

LED lights are environmentally friendly and consume significantly less energy while providing the same amount of light. They also have a longer lifespan and require less maintenance, resulting in fewer road closures for lighting repairs and, most importantly, safer roads for everyone.

We’ll work over five nights (9pm to 5am) between Friday 14 March to Thursday 27 March. 

This will be done in two phases, weather permitting. 

Closures and diversions
