The Severn Bridge is a key artery between England and Wales crossing over the River Severn and is essential to the economy of the country. The original Severn Bridge revolutionized transport in Wales when it was built. The link par excellence between land and water is represented by a bridge. The bridge has always been an undisputed symbol of passage, a critical but also a salvific place, as a symbol of unity: a bridge spanning a river connects one bank to the other and the Severn Bridge is only one of the many bridges (over one hundred) built in the past centuries to connect the two banks of River Severn. Some of them have become national monuments, such as the Atcham Bridge, the Over Bridge and the Iron Bridge. Severn Bridge, opened in 1966, replaced the ferry line between Aust (in England) and Beachley (in Wales). As the Queen said when she officially opened the bridge: “It offers a new economic era for South Wales”.
