Loose Viaduct

Loose Viaduct is a viaduct built in 1830 by Telford. It is constructed of dressed stone, with the soffit of the arch made of red brick in stretcher bond. The structure features a single elliptical arch that spans approximately 50 feet. At the base, there is a plain stone plinth, and the arch is formed by even, up-ended stone voussoirs that spring from tooled stone imposts. The arch is flanked by doubly-projecting pilasters that rise slightly above the parapet. Above the arch, there is a tooled stone plat band that extends over the pilasters. The parapet is plain, with stone coping that continues as a further plat band across the pilasters. There are short, curved flanking retaining walls that ramp down to single end pilasters. The west side has been cantilevered out in the 20th century in a similar style and materials to accommodate a footpath. The viaduct carries a turnpike road across the narrow Loose valley.
