Description

Tondu Road Underbridge is a railway bridge featuring a single span and a skewed masonry design. It has projecting wingwalls and is constructed from coursed and squared rock-faced sandstone, with rusticated voussoirs. The bridge retains an intact parapet made up of four uneven courses, with replaced coping on the upside. The downside has been reduced below the height of the parapet and is capped with engineering brick. Metal railings are present on both sides, and the wingwalls are plain and sloping.
