Croston Mill Bridge

Croston Mill Bridge is a road bridge built in the late 17th century and widened in the 18th century. It is constructed from sandstone and features a single span that measures approximately 11.9 meters, aligned north-south over the River Yarrow.

The east half of the bridge showcases a late 17th-century segmental arch with a projecting hood mould, accompanied by a stepped buttress on both the north and south banks. Rising from the apex of the arch is an 18th-century spandrel wall that includes three projecting masonry blocks for additional structural support, although it originally had five blocks, with two now removed.

On the west elevation, there is a simple segmental arch with voussoirs, and a string band runs along the parapet and wing walls. A central straight joint in the barrel arch and abutments indicates where the bridge was widened. The east half retains three stone corbels beneath the barrel arch, while the west half has four projecting masonry blocks. The roadway consists of a concrete saddle and tarmac surface, topped with an 18th-century three-coursed humped parapet featuring wing walls and saddleback coping. The inner face of the parapet coping stones is inscribed with ‘C C Croston Mill Bridge’. Additionally, three guard stones are positioned against the inner parapet, with two on the east side and one on the west.
