The northbound carriageway between the exit and entry slip roads, together with the A14 to M1 northbound entry slip road, will close on Friday, from 10pm to 6am. Traffic will be diverted via the M6 Northbound to junction 1, the A426 and A4303 to re-join the M1 at junction 20.
On Monday 30 June the southbound carriageway will be closed between the same points from 8pm to 8am with traffic diverted off the M1 at junction 20 and along the A4303, A4303 and M6 southbound to re-join the M1 at junction 19. Traffic wishing to travel east on the A14 will remain unaffected.
The closures are required to prepare the M1 to be put into contraflow. Barrier repairs are also being undertaken during the closures.
A contingency date of 1 July has been identified should either of the planned closures be postponed.
Further information about the project is available on the scheme’s website.
