Project information


We’re carrying out concrete repairs to the Tidmarsh Road bridge which spans the M4 and upgrading the barrier which protects vehicles from impacting the bridge. In order to carry out this work, it will involve accessing the bridge from the M4. 

To allow us to carry out the repair to the centre pier of the bridge, narrow lanes and a 50mph speed limit are in place on the M4 between junctions 12 and 13 in both directions. Free breakdown recovery is available.

Ensuring structural integrity and upgraded safety barrier.
