Forth Bridges
Forth Bridges, two parallel bridges that cross the Firth of Forth in Lothian, east Scotland. Spanning the river from the town of Queensferry on the south bank to Inverkeithing on the north, the Forth Bridge is a cantilever railway bridge which was opened in 1890. The nearby Forth Road Bridge is a suspension bridge completed in 1964. The railway bridge took eight years to build and at the time was the world’s longest bridge, being more than 1.6 km (1 mi) in length. The sheer scale of its cantilever design, containing 54,000 tons of steel, made it an engineering wonder, and it opened the way for a much-needed east-coast rail line to run from London to the north of Scotland. History relates that when the engineer who built it, Benjamin Baker, was asked how long the bridge would last, he replied: “For ever—if you look after it.” Repainting of the bridge has been continuously carried out ever since, and a well used saying to describe a never-ending task has arisen from this practice. A special paint was created for the Forth Bridge, which has been used since 1890, and gives the bridge its orange colouring. Looking slight by contrast, the more modern road bridge is a suspension bridge. Its main towers are 152 m (500 ft) tall, but it is shorter in length than the railway bridge, at just over 1 km (? mi). It provides a much-needed vehicular link between north and south Scotland. Both bridges emphasize the importance of the Forth crossing, where a ferry had run for 800 years until bridge design advanced sufficiently to provide alternatives. In their diverse ways the two Forth Bridges provide fine examples of engineering ingenuity and scale.
Forth Bridge, Scotland
The Forth Bridge, built in 1890, is the longest cantilever bridge in the world after the Quebec bridge (built in 1917), and is more than 1.6 km (1 mi) long in total, with two spans of 521.2 m (1,710 ft). It runs between Queensferry, outside Edinburgh, north across the Firth of Forth to Inverkeithing in Fife; in this view the Queensferry end of the bridge is in the foreground.
