A1 Biggleswade to Sandy
Date Added: 30/09/2022
update on the essential works planned to be carried out on the A1 between Biggleswade and Sandy.
Due to other works in the area, it has been decided to delay the works to avoid too many works occurring at the same time in the area.
It is now planned for the works to be completed over 4 months from Monday 24 October between 8pm and 6am on weeknights only, weather conditions permitting.
Closures and diversions
To carry out the work safely, parts of the A1 between the Black Cat Roundabout and Biggleswade North Roundabout will need to be closed, one direction at a time, and traffic will be diverted as detailed below.

A map of the diversion routes can also be found below.
