Tar Bridge

Three-arch humpback road bridge, built c. 1840, over River Tar at its meeting with River Glenboy, having rubble limestone walls, elliptical arches with roughly dressed limestone voussoirs, rubble limestone soffits, with concrete V-cutwaters to south elevation. Rubble limestone parapet walls with roughly dressed capstones to south and concrete coping to north. Rendered stile with limestone steps and concrete culverts to east end of north parapet. Pipe carried across south elevation.

The steeply rising humpback form with large arches raised high over the river level is reminiscent of the work of Samuel Jones, the nineteenth-century County Engineer, and similar to that of the nearby Goat's Bridge. The large dressed limestone voussoirs provide textural contrast to the rubble stone walls. The long parapet walls provide a sense of anticipation and serve to visually anchor the bridge in the landscape.
