Overview
- The bridge is shut in both directions between J1 (Aust) and J2 (Chepstow) because of strong winds, National Highways said.
- Drivers are being directed to use the M4 Prince of Wales Bridge as the alternative crossing.
- The South West Regional Operations Centre is monitoring wind readings to determine when it is safe to reopen.
- Reported guidance notes closure of the M48 at around 40 knots and potential shutdown of both crossings at around 70 knots for safety.
- Traffic diverted onto the M4 is causing localized slowing near junction 22 during blustery weather linked to Storm Goretti.
