The Highways Agency is giving road users advance warning of a 16-hour weekend closure of the M1 between Junctions 11 (Luton north) and 13 (A421, Bedford) in Bedfordshire while a bridge over the motorway is demolished.
The M1 will be closed in both directions between Junctions 11 and 13.The closure, scheduled for between 8pm on Saturday, 30 June and noon on Sunday, 1 July
Northbound traffic will be encouraged to leave the M1 at Junction 9 to prevent the A5/A505 junction in Dunstable becoming congested. Road users will be diverted from Junction 9 along the A5 through Dunstable and Milton Keynes, where it will join the A509 Portway and re-join the M1 at Junction 14. The diversion is expected to add 25 minutes to journey times.
Southbound traffic will be diverted from Junction 13 along the A421 to the A1, down the A1/A1(M ) to the M25 and either continue its journey or go back up the M1 to Luton. People should allow up to an hour for this diversion.
In the event of the work having to be cancelled, for example due to bad weather conditions, it will take place at the same times on the weekend of 21 and 22 July instead.
