Scope and Content Aberchalder Swing Bridge, Caledonian Canal, Highland, from west This shows the deck of the swing bridge which was built in the 1930s by Sir William Arrol & Company. To either side of the deck there are flashing warning signs and moveable barriers with octagonal-shaped 'STOP' signs which warn road users when the bridge is open. In the background there is a small cottage which would have been occupied by the bridge-keeper and his family. This bridge replaced an earlier swing bridge which had probably become too small for the greatly increased car usage from the 1930s onwards. The advantage of this new bridge is that it provides a stronger and wider span across the canal for road traffic. 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.
