|Route outline (key)|
The C1137 runs loosely parallel to the A86 on the south side of the River Spey. However, it is a narrow single track road and whilst it is shorter to the A9, and there are some long straights, it is slower than the main road. The western end of the road was originally built in the 1720s by General Wade as part of the Corrieyairack Pass route, although this turns southwards about a mile from the A9, and runs through the forest to Crubenbeg along forest roads and tracks.
The route starts on the A889 at the sharp bend at Catlodge, a little over a mile from the A86 junction at Drumgask, and heads west. A couple of long straights along the forest edge are followed by a windier section, before another straight. A few more bends lead to the junction where the C1137 leaves the military road behind, and it now heads north east past the Glen Truim estate, and over the river to meet the A9. The bridge is considered to perhaps be a Telford design, although whether it was built as part of his Commission on Highland Roads and Bridges, or later using the earlier plans is unclear. It is possible that the whole road was improved by Telford, as his commission assumed responsibility of the military road network.
