Sign at the northern end of the B9178
The B9178, formerly the highest-numbered road in the UK, is a short road between the A938 and A95 near Dulnain Bridge in Strathspey. It forms some of the southern section of what was the A95 through the village before the bypass of this route was constructed, the northern section becoming a continuation of the A938.
The number for this route isn't obvious on the ground or from mapping as the signs at its southern junction with the A95 suggest it is part of the A938 and signs at the junction with the latter don't include a road number at all. Ordnance Survey mapping also suggests that this road forms a spur of the A938; however, the Highland Council's list of adopted roads confirms that it is in fact classified as B9178.
The road starts in the village of Dulnain Bridge at a T-junction with the A938, which was previously the terminus of that road on the A95, next to the River Dulnain. Our road immediately crosses the river on the bridge from which the village takes its name.
The road heads south through a forestry plantation for around a third of a mile, after which a side road from the south, which was the original alignment of the A95, meets the road immediately before it terminates at a T-junction on the current route of the A95.
