A1 and A421 closures near the Black Cat roundabout this weekend

National Highways says the following roads will be closed from 9pm on Friday, September 4, until 5am on Monday, September 7.

The closures are:

> A1 northbound between Tempsford and Black Cat

> A1 southbound between Wyboston and Tempsford

> A421 westbound between Black Cat and Renhold Interchange

> Bedford Road between the Roxton Road turn-off and Black Cat.

This is so a new road layout can be installed at the Black Cat junction.
