M48 Central Barrier Replacement

Start Date:20/10/26 | End Date:31/03/27

M48 Barrier

Works to replace the M48 central barrier between the Dewstow Road Overbridge and the Crick Overbridge. These works will require lane 2 closures both westbound and eastbound

The work will be carried out at night between 20:00 and 06:00 Mon-Fri.

The works are being carried out overnight when traffic flows are historically lower to minimise disruption. Higher than usual levels of noise may be experienced. Please accept our apologies in advance. These works will enable the 50mph speed restriction to be removed when complete.

No diversions.
