Diversions announced as air ambulance attends serious collision which has closed the M1 at Milton Keynes

Police have closed the carriageway – leading to long delays of up to 45 minutes.

Drivers are being urged to avoid the M1 northbound between J11A (Leighton Buzzard) and J13 (Milton Keynes) due to the serious collision.

All emergency services are working at the scene with Bedfordshire Police leading the response at this stage.

An air ambulance also attended the scene, which also lead to the southbound carriageway briefly being blocked.

Continue for approx. 3 miles to the second roundabout.

Take the 3rd exit to continue on the A5 Watling Street heading northbound.

A Highways spokesman said: “If the closure impacts on your planned route, motorists are advised to allow extra journey time. Plan ahead, you may wish to re-route or even delay your journey.”
