The George Street Bridge is a road bridge over the River Usk in Newport , South Wales . It was the first cable-stayed bridge in Great Britain .
The four-lane George Street Bridge is 288 m long and crosses the River Usk in the course of George Street. It is extended to the west by an elevated road over Usk Way to the next intersection.
The bridge has a span of 152 m above the river and 68 m in each of the two side openings. Its two pylons each consist of two vertical, 52 m high reinforced concrete posts, which are only connected to one another by a crossbar under the bridge deck.
In each of the pylon posts there are three openings, one above the other, through which a double stay cable is led. On the outside, the ropes are stretched parallel to the bridge deck, so that visually a harp-shaped bracing with three stay ropes results. Each of the double cables is fanned out over the main opening so that two stay cables at different angles are stretched from each opening in the pylon posts to six attachment points on the bridge deck.
The total of 25.5 m wide bridge deck consists of a 20 m wide and 1.5 m high, multi-cell steel box girder , to which steel plates for the sidewalks protruding 2.75 m are attached.
The bridge was designed by Mott, Hay & Anderson (now Mott MacDonald ) with the local DP Cartwright office and built between 1962 and 1964. It was officially opened on April 4, 1964.
