East - Maintenance schemes

In late 2024 the culvert supporting the A1 over Billing Brook at Water Newton near Peterborough was damaged in a traffic collision.

As a result, we had to close the A1 southbound lane one over Billing Brook for safety reasons.

We need to temporarily re-align the A1 southbound so we can open two lanes for traffic while avoiding the damaged culvert

We started overnight preparations for main works from 1 September. On 12 September, we started realigning the carriageway.

We'll start repairing the damaged culvert in 2026-27. 

Temporary speed limit

We'll impose a temporary 40mph speed limit:

• while we work
• when we re-open two narrow lanes to traffic on the temporary alignment

Work delayed

Due to changes in our programme, there'll be no full closures on the weekend starting Friday 10 October.

After investigating the culvert structure, we need to do more design work. Unfortunately this will delay us. We now expect to finish realigning the A1 by the end of November.

One lane of the A1 southbound remains closed. 

Closures

When we're working, we'll need to close the A1 southbound between Wansford and Alwalton 

Diversion

If you're travelling southbound on the A1 through Wansford:

• exit the A1 at Wansford Interchange onto the A47 
• exit the A47 at Thorpewood Interchange onto the A1260 
• continue on the A1260 to Hampton Roundabout 
• turn right onto the A1139 
• rejoin the A1/A1(M) at Fletton Parkway Interchange

Work

We’re doing LED lighting surveys on the A120 Fentons Roundabout (Blake End Interchange) near Braintree. 

LED lights are better for the environment and use far less energy to produce the same amount of light. They also last longer and require less maintenance, meaning fewer road closures to fix lighting in the future and more importantly, safer roads for everyone. 

We’ll work only (8pm to 6am) on Thursday 9 October, weather permitting.  

This work is part of a bigger project to improve the A120 and M11. 

Closures and diversions

To work safely, We’ll need to close the exit and entry slip roads on the A120 Fentons Roundabout.
