A1 Black Cat roundabout work causing overnight closures on major roads near Cambridgeshire

Major roads will be closed overnight for works at the Black Cat roundabout from Thursday (April 25). The closures will be on the A1, A421, and Black Cat roundabout for three nights.

The closures will be in place on Thursday, Friday, and Saturday (April 25 to 27 inclusive) from 9pm to 5am. Diversions will be in place during the closures.

A National Highways spokesperson said: "As we continue with our work to upgrade Black Cat roundabout, the next step will be to install safety barriers, continue clearing the site of obstacles and carry out maintenance on CCTV cameras. These works will ensure that traffic can continue to use the A1, A421 and the Black Cat roundabout safely during construction.
