A40 Westway: From Sunday 21st July until October 2024 there will be a series of closures affecting the slip roads on and off the A40 at the Westway roundabout and on the A3320 West Cross route. This is due to critical safety works.
The first phase of these works will be from 22:00 on Sunday 21 July until Thursday 22 August, when the eastbound off-slip and the southbound A3220 West Cross route from the Westway roundabout will be closed. Drivers will not be able to exit the A40 to join the A3220 West Cross route travelling southbound. The westbound on-slip and A3220 northbound will remain open.
Signed diversion routes will be in place but these and local roads are expected to be extremely busy. Delays on the A40 Westway on the approach to the Westway roundabout and the exit for Wood Lane are expected.
Use alternative routes such as the A312 The Parkway or the A406 North Circular for connections with the A4.
