The work involves Anglian Water connecting a new watermain on Nags Head Lane close to the A1 carriageway.

For the safety of workers and motorists, the A1 northbound between Tempsford and Wyboston will be closed, and the A421 eastbound between Cardington interchange and Black Cat roundabout.

The closure will be in place from tonight 9pm Friday, October 10 to 5am Monday, October 13.
