M1 southbound junction 14 to junction 11a – roadside technology, resurfacing and maintenance works
I am writing to tell you that we plan to carry out roadside technology, resurfacing and maintenance works on the M1 southbound between junction 14 and junction 11a. This will ensure the M1 continues to remain in a safe and serviceable condition.
We plan to complete this work overnight on Friday 21 August 2026. We will work between 10pm and 5am, weather permitting.
