There will be full night closures on the M1 for bridge works:
Aug 8th & 9th Southbound closed at J12
10th & 11th Northbound closed at J11
22nd & 23rd Southbound closed at J12
24th Northbound closed at J11
Closures are 22:00 - 05:00
When one c/way is closed, opposite c/way is single lane running so expect delays on diversion route which is Toddington, Houghton Regis to J11 and vice versa for Northbound.
