M4 motorway bridge over the Severn Estuary in the United Kingdom

For the Canadian bridge formerly known as Prince of Wales Bridge, see Chief William Commanda Bridge.

The Prince of Wales Bridge (Welsh: Pont Tywysog Cymru), previously the Second Severn Crossing (Welsh: Ail Groesfan Hafren) until July 2018, is the M4 motorway bridge over the River Severn between England and Wales, opened in 1996 to supplement the traffic capacity of the Severn Bridge built in 1966.

The bridge is operated by England's National Highways. It has a total length of 5,128 metres (16,824 ft).

Severn bridge directions

It is southwest of the Severn Bridge and because it is more closely in line with the rest of the M4, it reduces the length of the journey between England and Wales. The junctions at each end are designed for most traffic to use this crossing, and in order to use the old Severn Bridge, one has to leave the M4 at junction 21 and join the M48 near Aust or at junction 23 near Magor.

The new crossing carries more traffic than the Severn Bridge, which is still in use. It is wider
