National Highways - UPDATE: Important roadwork information
A1 southbound between Buckden and Hail Weston Bridge – maintenance work
Dear Customer
We’re writing to let you know that we are moving onto the next phase of maintenance work on the A1 which will between Buckden and Hail Weston Bridge. This work will involve renewal of road markings and road studs also known as cat’s eyes, crack repairs and replacement of marker posts. Once complete, drivers will benefit from a safer, smoother and better-defined road surface.
We will carry out this work over four nights from Thursday 4 June 2026. We’ll work overnight between 9pm and 5am on weeknights only, weather permitting.
We have identified further maintenance work that needs to be completed. We’ll need additional night shifts towards the end of June. We’ll share more details about these dates as soon as they are confirmed.
Closures and diversions
To carry out the work safely, we will need to close the A1 southbound between Buckden and Hail Weston Bridge, and divert traffic as detailed below:
Drivers travelling southbound on the A1 should:
leave the A1 at Brampton Hut Interchange and join the A14
continue on the A14 to junction 23, Ermine Street Interchange
take the third exit onto the A1198
continue on the A1198 to the A428 / Ermine Street South roundabout
take the third exit onto the A428
continue on the A428 to Wyboston Roundabout
take the first exit onto Great North Road
rejoin the A1 southbound
The crossover at Diddington will stay open for access to the village, so northbound traffic will not be affected.
A map of the diversion is enclosed.
