Please be advised that the M4 between junctions 18 and 19 will be closed in both directions from 19:00 on 21st March. The motorway will re-open at 06:00 on 24th March.

The motorway is being closed to allow for the A432 Badminton Road bridge over the motorway to be demolished.

Local diversions will be in place, using the M32, A4147, A420 and the A46.

Delays are expected, with in excess of 80,000 vehicles expected to be diverted during the closure.

The partial M4 motorway closure will affect road freight shipments transiting the Bristol area, so please contact your local office to discuss any shipments you currently have, and the team will be on hand to assist with any queries.
