Work to demolish a bridge over the M1 at Junction 12 will mean closure of the motorway and diversion routes in place for those travelling to London Luton Airport at the end of June. The closure will take place from 22:00hrs on Saturday 30th June until 12:00 midday Sunday 1st July.
Traffic travelling south on the M1 will be diverted off the motorway at J13 along the A421 to the A1M. If travelling to London Luton Airport, traffic will be diverted from J13, along the A421 to Elstow to pick up the A6 into Luton.
Traffic travelling north will be advised to exit the motorway at J9, take the A5 to Milton Keynes and then rejoin the M1 at Junction 14. If travelling to London Luton Airport, traffic will be allowed to stay on the motorway as Junctions 10 and 11 will still be open to local traffic.
