Important roadworks information
A1 Biggleswade North Roundabout to Sandy Roundabout – resurfacing
I’m writing to tell you that we plan to carry out resurfacing on the A1 northbound between Biggleswade North Roundabout and Sandy Roundabout. Once complete, drivers will benefit from the A1 remaining in a safe and serviceable condition.
We plan to complete this work over two nights starting Wednesday 17 June 2026. We will work between 9pm and 5am, weather permitting.
Closures and diversions
To carry out the work safely, we will need to close the A1 northbound between Biggleswade North Roundabout and Sandy Roundabout and divert traffic as follows:
- From Biggleswade North Roundabout, head southbound on the A1 to Baldock Services (Junction 10 A1(M))
- Traffic will be diverted off the motorway at A1(M) junction 10
- Following the A507 to Clophill Roundabout, take the third exit onto the A6 northbound
- At the Elstow Interchange take the fourth exit onto the A421 eastbound to the A1 Black Cat Roundabout
- At Black Cat Roundabout, head north to Wyboston, take the exit slip on Great North Road
- At the A428 Wyboston Roundabout take the fourth exit and return southbound on the A1
- Continue Southbound to Sandy where the diversion ends
A1 Southbound Beeston local diversion:
- Traffic should continue southbound on the A1 and take the first left onto Station Road into Sandy
- Follow the B1042 to the A603 roundabout, then onto Vinegar Hill and finally Beeston Road
Resident Access – via Upper Caldecott on the route below
Residents will be given access via Biggleswade Road on the A1 following the route below:
