Invernauld Bridge

Invernauld Bridge crosses the Allt Mhor on the A837 at the western end of the village of Altass. It is a single stone arch spanning high above the stream, and was most probably built by Joseph Mitchell in the 1820s as part of his road building work for the county of Sutherland. The Allt Mhor here has cut a steep ravine, known as Ravens Rock Gorge further to the north, and so the abutments for the bridge are tall and shallow. Pilasters rise up either side of the arch to the parapet, and unusually also show on the inside of the parapets. A string course also crosses above the arch, and small 'buttress stones' sit at regular intervals along the roadway against the parapets and wing walls. These last curve away at either end of the bridge, opening out to accommodate the junctions on either bank.

Overall, the detailing is relatively minor, but the effect is strangely elegant, perhaps reflecting that Mitchell had to tread a fine line between the County's bank balance and the aesthetic demands of the neighbouring land owner, after who's Invernauld House the bridge was named. The road across the bridge is just about wide enough for two cars to pass, but as it continues north west it widens out to S2, having been single track to the east.
