Planned closures

The A421 will be closed between the Eagle Farm Roundabout up to M1 Junction 13 near Magna Park from 10pm on Thursday 12 December and will open at 6am on Friday 13 December at 6am.

The road will also be closed from 9pm on Friday 13 December and will open at 6am on Monday 16 December.

These closures will allow us to carry out works at Cranfield Road bridge.

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.
