Description

This is a single-span, double-carriageway bridge built from snecked rubble, featuring a segmental arch with cut voussoirs. The bridge is framed by plain pilasters that support a raised band below the parapet. On the outer sides of the pilasters, there are pierced roundels. The parapet is partly missing on the south side, where it is heavily overgrown, and it has a replaced concrete coping.
