Popis
The bridge is constantly moving. It bends more than three metres in the middle in winds of 80mph and the towers bend inwardly at the top.
A total of 480,000 tonnes of concrete were used to build the bridge.
The bridge towers are 36mm (1.4 inches) further apart at the top than the bottom to take account of the curvature of the earth.
The main cable contains 11,000 tonnes of steel wire - enough to stretch one and a half times around the world, a total of 43,000 miles.
The bridge held the world record as the longest single span suspension bridge for 17 years.
