From National Highways:

Our preparation work to install traffic management will begin on 29 October. 

This work will focus on installing safety barriers, temporary CCTV cameras and crossover locations, and will allow us to put in place a contraflow system in November.

So our teams can safely carry out this work, the following overnight closures will be in place:

29 October: A40 eastbound closed between Dixton roundabout and Whitchurch

30 & 31 October and 1 & 4 November: A40 westbound closed between Whitchurch and Dixton roundabout

This means that the westbound carriageway will be reduced to one lane from 6am on the morning of 31 October 2024. A free recovery service will be in place during this time. 

Clearly signed diversion routes will be in place for both HGV and long-distance traffic. 

View diversion routes.

Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England website. Our travel alerts give details of live incidents on our network.
