Description
Kilmahog Bridge is a two-arch, rubble bridge over the Garbh Uisge, located just east of the Falls of Leny. It was built in 1777 by the mason Peter McInnes from Crieff, under the direction of the Commissioners of Forfeited Estates as part of an improvement scheme for the forfeited estate of the Duke of Perth, following the 1745 Jacobite uprising. This bridge is a well-preserved example of late 18th century architecture.
The bridge features two segmental arches made with vertically set narrow voussoirs, which are separated by a pointed, piended cutwater. On the southeast face, there are two shallow, sloped buttresses flanking the arches. A corniced ashlar date plaque is located on the northwest face. The abutment and parapet are constructed from random rubble, and there are mid to late 20th century iron railings on the parapet. The road surface is modern, having been paved with tarmac in the late 20th century.
The materials used in the construction include random rubble, squared rubble voussoirs, and cutwaters.
