The viaduct is 120 feet (37 m) high with twelve 60 feet (18 m) wide arches, and a further small arch in the Calstock abutment. Three of the piers stand in the River Tamar, which is tidal at this point and has a minimum clearance at high tide of 110 feet (34 m).
It was built between 1904 and 1907 by John Lang of Liskeard using 11,148 concrete blocks. These were cast in a temporary yard on the Devon bank opposite the village. The engineers were Richard Church and WR Galbraith.
