The Severn Bridge actually spans the Severn Estuary and the River Wye so it is in fact two bridges. With increased congestion, closures due to high winds and accidents it was decided that a second bridge would be needed to cope with the increased traffic flow. The photos that you see here are taken whilst crossing the bridge, that is, the original Severn Bridge on the M4.
In 1992 Royal Assent was given which enabled the concession and construction of the new bridge which was opened by His Royal Highness, The Prince of Wales on 5th June 1996.
