History

The dock upstream from the bridge was begun in 1833, but financial troubles meant it was only finished between 1869 and 1875, and is nearly rectangular with a quayage of 3,860 feet (1,180 m) and an area of 10.7 acres (4.3 ha).[1] The bridge was built between 1871 and 1874 to service the new docks.[2] It was engineered by Rendel and Robertson, with J. H. Bostock as resident engineer.[2] McDonald & Grant were contractors for the foundations, and the bridge was built by the Skerne Iron Works.[2] The works cost around GB£30,000.[2]

Until the completion of the Kincardine Bridge, also in Scotland, in 1936, it is thought to have been the longest clear swing bridge span in Britain[2] (The Swing Bridge, River Tyne, completed two years after the Victoria Bridge, has a longer deck span).

After restoration, it was reopened on 22 November 2000 by Eric Milligan, Lord Provost of Edinburgh.[3]

Design
The footpath on the north side of the bridge

It was 212 feet (65 m) long in total, with a clear span of 120 feet (37 m), and a roadway width of 24 feet (7.3 m).[2] The bridge was constructed from wrought iron, and weighed 620 tonnes (610 long tons; 680 short tons), including 60 tonnes (59 long tons; 66 short tons) of timber decking and 240 tonnes (240 long tons; 260 short tons) of kentledge counterweight.[2] The bridge carried two tracks of a dock railway and a road, and there are footpaths on either side outside the truss structure.[2][4] The tracks and roadway have now been removed, and the bridge has a wooden deck.[4]

The bridge was powered hydraulically by a power station just to the north.[5][6] It swung to the north, and the space afforded for the counterbalance can still be seen.[6]

It has been succeeded by a new bridge further downstream, which carries a roadway known as Ocean Drive.[7][6]
