Torgyle Bridge

Torgyle Bridge is a large, three-span bridge built in 1823 by Joseph Mitchell, following an earlier design by Thomas Telford from around 1811. The bridge features a centre arch that is slightly wider and higher than the others. It is constructed from tooled and pinned rubble with tooled ashlar dressings. The bridge has three segmental-headed tooled ashlar rings, with the dressings made of alternating blocks of dark schist and lighter granite, which spring from rusticated masonry cutwater abutments.

The cutwaters rise as engaged columns that diminish in size and are decorated with dummy vertical and cruciform slits, finishing at parapet level with simple blocked caps. The end pilasters are similarly detailed. There is a band-course and tooled ashlar parapets with slightly splayed approaches. The approximate widths of the arches are 48 feet, 55 feet, and 48 feet. Drystone embankments flank the bridge.
