The Forth Road Bridge

The Forth Road Bridge The Forth Road Bridge seen from North Queensferry The middle of the three bridges over the Firth of Forth, in both position and age, is the Forth Road Bridge which was opened in 1964. The two road bridges The Forth Road Bridge with the new Queensferry bridge beyond Although it had been talked about for a century or more, work actually started on The Forth Road Bridge in 1958, by then the pressure on the 800 year old ferry service, which was carrying some 1.5 million people a year, was intense. The bridge was chosen in preference to a tunnel for its lesser cost. Now most people seem to welcome the design style with its contrast to the rail bridge. Its vital statistics are that it rises 150 metres above the water, has a total length of 2.5 kilometres, with a central span of just over one kilometre. road bridge and ferry pier The road bridge with the pier of the ferry it replaced Road and rail bridge The road bridge with the rail bridge beyond Under the road bridge Looking under the road bridge, the reflection of its carriageways on the water Looking up under the north tower Both carriageways have combined footpaths and cycle ways The two cables on which the bridge is hung are nearly two feet (0.59 metre) in diameter and consist of some 11 thousand wires (each nearly a quarter of an inch thick) wound together. These two massive cables each carries 13,800 tons, so the road bridge has half the weight of the rail bridge.

The original cost was £11.5 million.
Seven workers' lives were lost during building.

Road and rail bridges The road and rail bridges form a magnificent pair,
contrasting slender economy with massive strength
