[1] When the canal was shortened in 1922 to make Lochrin Basin the terminus it was moved to its present site to replace a wooden drawbridge.

[2] A report published in the year 2000 had suggested fixing it permanently open, but the decision was taken to restore it to full working order.

[3] The restoration involved removing the deck and the top member of the bridge to access the inner workings.

[2] It is formed from riveted steel, with more substantial columns on the southern side where the motors and counterbalances are housed.
