It is 8.2m wide, and carries standard gauge double tracks up to 30m above the ground, with 18 spans up to 226 ft (69 m) long; six of the spans are over the river valley, with the remainder continuing on the east side of the valley as a lower elevated section. It was the first structure in Britain to be built using cantilevered concrete sections with joints glued with epoxy resin.
