HS2 Works Notification: M40 Junction 11, new traffic signal installation

We’re writing to let you know about some planned works that we will be carrying out in your area.

We need to close the M40 at Junction 11, southbound exit, between the hours of 8pm to 5am at some point during a one-week period between the 2 July and 9 July 2022 (inclusive of the weekend). The works are only expected to take one night, but are weather dependent. we need to be able to safely complete the installation of road surface ‘loops’ for the new traffic signals to the motorway slip lanes and ‘A’ road approaches on the M40.

The night-time closure will require drivers wishing to exit southbound at Junction 11, to continue on the M40 to Junction 10, and use the diversion to re-join the M40 heading northbound and exit Junction 11 on the northbound side.

Please see details of the works here:
