Forth Road Bridge cable repairs

When the Forth Road Bridge opened in 1964, it was the longest span suspension bridge outside the USA and the fourth longest in the world. Faber Maunsell, in conjunction with Weidlinger Associates of New York, was appointed by FETA to carry out the cable inspection during 2004/5 which unexpectedly revealed widespread corrosion, broken wires and a strength loss of 8 to 10%, with future strength predictions suggesting traffic restrictions as early as 2014. Faber Maunsell has devised a solution to the severe corrosion in the main cables of the bridge by injecting dry air into them. This article discusses this groundbreaking alternative solution to the conventional protection system.
