M4 Prince of Wales bridge resurfacing

Start date: July | End date: Autumn 2024

M4 Severn Bridge National Highways

National Highways need to re-waterproof and resurface a 1km stretch of the cable stay bridge to extend the life of the road surface.

They aim to maintain as much capacity as possible by keeping 2 lanes running in both directions and offering the M48 Severn bridge as an alternative route. 

 

The latest programme dates will be published on the National Highways website here.

 

The M48 Severn bridge will be used as the diversion route. Further details are available via National Highways.
