Mouth Bridge

Mouth Bridge, built around 1795, is a single segmental-arched bridge with a symmetrical hump and long ramped approaches on the southwest and northeast sides. It is constructed from sandstone rubble, featuring broadly droved dressings on the voussoirs, arch ring, coping of the parapet, and terminal dies. The bridge has rock-faced ashlar below the impost bands of the arch. A mutuled cornice rises to a point at the center, leading to a coped parapet. The walls on the east and north sides end with drum piers or dies, while the south and west sides have quadrant walls. The wing walls step inward towards the center, and the walls are buttressed, with most of these features added shortly after the bridge was built, except for a southeast buttress added in 1945. A plaque on the southwest elevation, on the roadside of the parapet, notes that the bridge was restored in 1992 by Borders Regional Council.
