The Highways Agency are advising drivers that one lane of the southbound M1 in Northamptonshire will remain closed through today.
The closed lane affects a short section of road between junction 17 (where the road meets the M45 south of Rugby), and junction 16, for Daventry.
The closure is necessary as a road surface defect that was being repaired overnight was larger than expected and requires more time to repair. A full repair will be made overnight tonight.
Drivers planning to use that section of the M1 today are advised to check conditions on their route – especially if they are travelling at peak times – and leave more time for their journey if necessary.
