Planned closures

The A421 between the Eagle Farm Roundabout up to M1 Junction 13, will be closed temporarily on these dates:

  • Friday 3 April from 8:00pm until 6:00am Monday 6 April
  • Friday 10 April from 8:00pm until 6:00am on Monday 13 April

Diversion routes

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.A421 closed diversion route 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.Cranfield road bridge diversion

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.
