General notes:
John Powell reports that Muirtown Bridge, which carries the A9, is owned by British Waterways and built in the 1930's by Sir William Arrol Contractors (of Forth Bridge fame) as a half through steel girder counterweighted swing bridge with steel buckle plate decking and surfaced with tarmacadam. The bridge was fairly wide with two way carriageway and raised pedestrian footpath.

The buckle plate deck tended to flex under traffic loading causing lots of resurfacing works. Deck strengthening works were undertaken in 1976 and again in 1980 but only with limited success. Eventually a major strengthening contract was undertaken in 1989 by Fairclough Scotland Contractors which involved removing the steel buckle decking and replacing with a lightweight concrete deck. This seems to have solved the problem.

In January 2009 it was reported in 'Canal Boat' magazine that all locks and movable bridges on the Caledonian are keeper operated, and are subject to specified working hours that vary with the seasons - summer working hours are 0800 to 1800 daily; spring and autumn 08.30 to 17.30 daily; winter 09.00 to 16.00 Monday to Friday only.
