There will be a number of overnight road closures in place on the M4 this week, including near Newport, which are set to cause disruptions.

These M4 closures come as a result of maintenance, resurfacing and environmental works and will affect sections near areas including the Prince of Wales Bridge, Bridgend and Swansea.

These closures come following the closure of the Severn Bridge on the M48 on Sunday (November 19). 

The Severn Bridge was closed in both directions just before 10am on Sunday between junction one for Aust and junction two for Chepstow. 

The bridge was closed as a safety measure due to very high and strong winds.

As we look ahead, these are the sections of the M4 that will experience road closures this week (November 20 to 26, 2023).
