The M48 motorway is a major road in the United Kingdom that connects England and Wales. It runs from Chepstow in Wales to Bristol in England, crossing the Severn Bridge over the River Severn. The motorway is approximately 11 miles long and serves as an important route for both local and long-distance traffic. Opened in 1966, the M48 motorway was the first crossing of the Severn and has since facilitated trade and travel between the two countries. It is part of the UK motorway network and is designated as a key route for heavy goods vehicles and commuters alike.
