The M4 Prince of Wales bridge was closed for emergency work on Sunday after torrential rain wore down repair work.

The bridge was closed westbound between J21 (M48 Split) and J23 (Rogiet) for 'emergency carriageway repairs,' according to National Highways, and drivers are being diverted to the M48 Severn Bridge.

National Highways has attempted to make repairs to the carriageway overnight and into today but the work has been hampered by spells of torrential rain.

A spokesperson for National Highways said: "The repairs will now take place later today and overnight with a window of better weather expected.

"If this closure impacts on your planned route, please allow extra journey time.

"Plan ahead and check traffic conditions before setting out on journeys as congestion is likely on routes approaching both bridges including along the M4, M5 and M49 motorways."

"Further information is available from National Highways by visiting our website and travel apps, or via our regional X feed.

"Our 24/7 contact centre team is also available to provide up to the minute information on 0300 123 5000."

The work was expected to be completed by 6am on Monday.

Westbound traffic was diverted via the M48 Severn Bridge.
