Borrodale Bridge
(Institute Civil Engineers Historic Engineering Works no. HEW 0021/03)
Borrodale Bridge has three arched spans, the central one of 127 1/2ft was said to be the longest concrete arch in the world when built. Its soaring unreinforced-concrete arch, built on a curve in plan, exudes confidence. The rise of the arch is 23 ft and its height above the burn is 80 ft. Its arch-ring, composed of concrete comprising four parts sand and stone to one part cement, is 4 1/2ft thick. The 20 ft side spans were clad in masonry and the bridge was given castellated masonry parapets to mollify a local landowner.
