The works, which will take place at the junction of the A40 and Wales Farm Road, will see the A40 be reduced to two lanes eastbound.

Drivers are advised to find alternative routes and avoid using the A40 between Hanger Lane and the A40 Westway where possible.

Current work to replace the A40 bridges at Wales Farm Road and Perryn Road, which is being carried out separately by TfL, will be continuing as normal while the work by EDF Energy is completed.
