The famous Forth Road Bridge celebrated its 50th anniversary last weekend with a spectacular fireworks display.
Construction of the bridge began in 1958 and was completed in 1964, with the 1,006-metre span structure becoming the longest span suspension bridge outside of the US and the fourth-longest in the world.
This bridge carries over 24m vehicles each year, and a new bridge, the Forth Replacement Crossing, is under construction now to ease the burden.
The pictures above were provided by Aecom, which has been involved with the bridge since 2003. After major inspection of the bridge and main cables, Aecom Transportation developed and installed a cable dehumidification system to help extend the bridge’s lifespan.
