Shangan Aqueduct/Torcastle Aqueduct

One of five constructed by Simpson & Wilson by 1808 on the 6-mile reach of canal between Banavie Locks and Loch Lochy. The Shangan Aqueduct of similar construction to Loy Aqueduct (NN18SW 3.01) had and still has three spans of 10 ft. Bothwere rebuilt as part of the 1843–47 re-furbishment.

This work was done as a precautionary measure after the Upper Banavie Aqueduct, 12 miles south of Shangan, had collapsed in 1843 emptying this reach of the canal.
