East - Maintenance schemes - National Highways

You can view more details about the maintenance schemes taking place in the East below:

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've completed temporarily re-aligning the A1 southbound. This has allowed us to open two lanes for traffic while avoiding the damaged culvert.

We'll need overnight closures on the A1 southbound for some works in December.

We'll start permanently 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

Closures

Monday 15 and Tuesday 16 December - A1 southbound between Wansford and Alwalton

Fully closed overnight (9pm to 5am).

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
re-join the A1/A1(M) at Fletton Parkway Interchange
