Scope and Content Tomnahurich Swing Bridge, Caledonian Canal, Inverness, Highland, from east This shows part of the support for the swing bridge, designed by Crouch & Hogg and T Shirley Hawkins, which was built in 1938 by Sir William Arrol & Company. Wheels attached to the underside of the bridge run along the tracks (left and under the bridge on the right) during the opening and closing operation. The bridgekeeper would operate the controls for the bridge from the square building in the background. Originally, another movable bridge spanned the canal at this point which probably became out-dated or too weak for the volume of traffic. The control cabin is part of the original design, which is unusual, as most of the other 1930s swing bridges over the canal have cabins which were added in the late 20th century. The Caledonian Canal was designed by Thomas Telford (1757-1834) and built between 1803 and 1822 at a cost of £840,000. It was the first example of a transport network funded by the government in Great Britain. The 96.5km-long canal provides a route for boats travelling between the North Sea and Atlantic Ocean as it runs from the Beauly Firth at Clachnaharry, Inverness, to Loch Linnhe at Corpach. Only 35.4km of this length is man-made while the other 61km runs through four lochs: Loch Dochfour, Loch Ness, Loch Oich and Loch Lochy. Unfortunately, at 4.2m deep, the canal was too small for most sea-going ships which led to it being altered and deepened between 1844 and 1847. Source: RCAHMS contribution to SCRAN.
