The Forth Road Bridge is a suspension bridge crossing the Firth of Forth in Scotland. It connects the city of Edinburgh to Fife. The bridge carries cars and pedestrians across the Firth. It was built in 1963. Trains use the nearby Forth Rail Bridge, a historic railroad bridge built in 1890. The bridge was designed by architect Richard Gilbert Scott.
Repairs[change | change source]
Even though the bridge was built so recently, it has had some serious repairs done. A report into the failure of nine heavy-duty nuts on the Forth Road Bridge said all 1,888 similar nuts on the crossing should be replaced.
All the cable band nuts and bolts were replaced in the late 1990s as part of a large project to replace the hanger ropes. Ten years later, a report found serious defects. Bridge authority FETA investigated when inspectors found the nine cracked nuts. Engineers FaberMaunsell carried out lab tests and a study of similar issues on suspension bridges across the world. The nuts are used to secure 192 'cable bands' to the bridge's main cables.
Engineers have now replaced all nuts and bolts which were cracked.

- The bridge is a suspension bridge. They are held up by cables attached to the river banks and 'piers' sunk vertically in the ground beneath the water.
- Nuts and bolts are fixed to the metal frame with rubber washers which allow some 'give' as the bridge moves under loads from wind and traffic.
