Road users are advised that the M4 will be closed in both directions between junction 5 (for Langley) and junction 6 (at Slough) this weekend to lift steel beams for the new Riding Court Road bridge into place.

The motorway will close from 8pm tomorrow (Friday) to 6am on Monday.

Motorway traffic will be diverted via the A4 and A355 during the closure. Other traffic should follow local diversions. All diversions will be clearly signed.

Traffic volumes on the M4 have significantly reduced as people follow Government advice to stay at home to stop the spread of coronavirus. But anyone making an essential journey who will be affected by the closure should leave extra time for their journeys and consider alternative routes if possible.

The work is part of a project to upgrade the M4 between junctions 3 and 12 to a smart motorway. For more information and to sign up for project newsletters please visit:
