Diversions and closures
A421 closure dates
There are no scheduled closures at this stage of the project. Sign up for email alerts to get the latest information, including road closures.
We will only make closures when the M1 road is open. However, our diversions show the alternative routes for drivers who can’t or who don’t want to use the motorway.
There is a diversion route for drivers who would normally take the A421. This route avoids villages and goes via the A421 Bedford Western Bypass and then the A422 towards Milton Keynes.
There is also a diversion route for those who would normally take the Cranfield Road.
The lorry restrictions remain in place for the local villages.
Temporary closures to public rights of way will be in effect during the work.

We apologise for any inconvenience caused, and thank you for your patience during the roadworks.
