A crash has caused partial closures on the M4 Prince of Wales Bridge.
Highways England reported a traffic collision at around 10.30am, closing the M4 Westbound at Junction 22.
As of 11am, lane three remains closed in both directions while barriers are repaired.

"We would still advise using the M48 as an alternative route at this time," wrote Highwas England on Twitter.
