Description
The Forth Road Bridge is one of the world’s most significant long span suspension bridges. With a main span of 1006 metres between the two towers, it was the fourth longest in the world and the longest outside the United States when it opened on 4 September 1964.
In total, the structure is over 2.5 km long. A staggering 39,000 tonnes of steel and 125,000 cubic metres of concrete was used in its construction.
The Forth Bridge (Rail Bridge) first opened in 1890 and is a marvel of Victorian engineering. The overall length of the Forth Bridge is 2,467 metres and the main structure (portal to portal) measures 1,630 metres. The highest point of the Forth Bridge stands 110 metres above high water and 137 metres above its foundations.
53,000 tonnes of steel and 6.5 million rivets were used to construct the Forth Bridge and the Forth Bridge's piers are constructed from 120,000 cubic yards of concrete and masonry, faced with 2 ft thick granite.
200 trains use the bridge every day, carrying 3 million passengers each year.
