SX3974 : Horsebridge from the Cornish SideFrom Charles Henderson's
Old Cornish bridges and streams (1928, reprinted 1972):
"Horse Bridge ... bears a close resemblance to Greyston but it is larger and higher. There are six big round arches 20 feet in span and 17 feet high. The spring from imposts 9 feet above the water. The river is 5 feet deep and the central piers, from bed to parapet, measure 30 feet. There is a small floodwater arch at the Cornish end 20 feet in span. The bridge measures 200 feet in length from arch to arch with 50 feet more of causey at the Western end. Until a recent flood, this causey extended far across the green meadows. The road is only 12 feet wide, as it was in 1809. The bridge is built of local stone with freestone dressings as at Greyston. its most remarkable feature consists of curious stone brackets projecting from the angles of the upstream cutwaters near the top. These brackets are some 20 feet above the water level and are an integral part of the building, being well executed in freestone with notches or grooves cut underneath them, apparently for the holding of wooden poles. It is possible that the brackets were connected with a Salmon Weir or stake net. Perhaps Horse Bridge marked the lowest limit of the Abbot's fishery. "
