Overview
- The A40 will shut in both directions between the Westway roundabout and the Marylebone flyover from 22:00 on March 20 until late April.
- TfL reports parts of the structure have reached the end of their service life, with two expansion joints being renewed to maintain safety.
- The route carries up to 96,000 vehicles a day, and TfL warns of significant disruption with a traffic signal strategy to manage flows.
- Drivers are advised to use the M4 and A4 for M25-to-central London journeys or the A312 or A406 for outer-London-to-central trips, and to check affected bus services.
- Following this phase, westbound traffic at the Westway roundabout faces weekend closures excluding bank holidays until July 6.
