The M48 is a 13-mile (21 km) long motorway in Great Britain, which crosses the Severn near Chepstow, Monmouthshire, linking England with Wales via the Severn Bridge. This road used to be the M4, and as a result is anomalously numbered: as it lies to the north of the M4 and to the west of the M5, it is in the Motorway Zone 5.[1][2] The M4, M48 and the A48(M) motorway are the only motorways in Wales.[3]
Route
Travelling from east to west, after leaving the
.Junction 2 can be reached via the A466, which leads to the A48. The junction gives access to the Wye Valley, an Area of Outstanding Natural Beauty. When travelling either east or west on the M4, the M48 is the more direct route for Chepstow and Caldicot.

toll-free since 17 December 2018
The M48 was opened as part of the M4 in 1966.[4] Before this date traffic between South West England and South Wales was either transported on a motorail service through the Severn Tunnel, used the Aust Ferry (which was unsuitable for large goods vehicles) or travelled through Gloucester to pass north of the Severn Estuary.[5] The route became increasingly busy and in 1984 a report was commissioned.[6] After four years of construction, the Second Severn Crossing was opened in 1996 and was designated M4.[4] The original stretch of motorway was designated M48 and continues to link England and Wales. Since 17 December 2018, both crossings have been toll-free.[7]

Services
Severn View services are at junction 1, formerly called Aust Services when originally opened, and may also be accessed via the A403 from Avonmouth. There is a footpath leading from the services to allow pedestrians to cross the bridge. When the M4 was diverted over the Second Severn Crossing, it was anticipated that these services may close. The original building offered views of the River Severn. It was sold and operations continue in a new, smaller development on an adjacent site nearer the motorway junction.[9]
