In the late 1960s, traffic was becoming a challenge for the industrialized area around Glasgow, Scotland. Crossings of the River Clyde were desperately needed to provide access for shipbuilding and other industries in the booming region. The Erskine Bridge, a 1.3-kilometre box girder structure across the Clyde, was built over three years and opened in 1971. This mid-1970s documentary shows the unique and innovative methods used in the design and construction of the Erskine Bridge.
