World's Greatest Bridges S01E06 - The Severn

Rob Bell explores the history and construction of the world's iconic bridges. Opened in 1966, the Severn Bridge was the first road bridge to connect England and South Wales by spanning the vast Severn estuary. Rob reveals why its design by Dr Bill Brown revolutionised the way that modern suspension bridges are built. He also surfs the Severn Bore and meets the construction workers who braved the wave and tidal ranges of up to 50 feet in order to build it.
