Lyne Viaduct

Probably by Robert Murray, 1864, on Symington, Biggar and Broughton Railway. 4-span viaduct, 3 cream skew-arched spans each of 29? sandstone masonry over Lyne Water, single wrought-iron plate girder span over minor road at W end. Masonry spans have depressed arches with polished ashlar spirally cut soffits, rock-faced voussoirs and spandrels. Piers have rounded cutwaters supporting tapering semi-octagonal buttresses extending through cope to form dies for cast-iron geometric railings. Massive abutment at road end of masonry section has 3 buttresses on upstream, 2 on downstream side to allow for skew. All buttresses have blind cruciform ?arrow slits?.
