Lyne Viaduct

Lyne Viaduct, probably designed by Robert Murray in 1864, is located on the Symington, Biggar and Broughton Railway. This four-span viaduct features three cream skew-arched spans, each made of sandstone masonry, spanning 29 feet over the Lyne Water. At the western end, there is a single wrought-iron plate girder span that crosses a minor road. The masonry spans have depressed arches with polished ashlar soffits that are spirally cut, along with rock-faced voussoirs and spandrels. The piers are equipped with rounded cutwaters that support tapering semi-octagonal buttresses, which extend through the cope to create dies for cast-iron geometric railings. At the road end of the masonry section, there is a massive abutment with three buttresses on the upstream side and two on the downstream side to accommodate the skew. All buttresses feature blind cruciform arrow slits.
