The Bridge of Mucomir carries the B8004 over the River Lochy just a few yards after the river leaves Loch Lochy. The bridge was built in c1815, not to carry a new road over an old river, but to carry an old road over a new river! This new channel for the Lochy was dug by Telford's team when the Caledonian Canal was built, taking over the old river channel. This forced the River Lochy into the River Spean somewhat sooner than previously!
The bridge is a lofty 2-arch structure, carrying the road in a slightly awkward kink. The road is wide enough for two cars to pass, but the approaching bends are both a bit too tight, forcing traffic to slow. Immediately up stream - there is just enough room before the loch - is another bridge, providing access to the Hydro Power Plant.
