Full description

Steeperton bridge, clapper bridge. An old bridge spanning River Taw in its narrow gorge at foot of Steeperton Tor. It crosses the river obliquely. There are three piers between the two terminal supports and they are composed of rather flat stones. The piers were 1.2 metres above water in a moderate stream. The central one is 1.0 metre wide, the two western ones 900 millimetres, and the two eastern ones 750 millimetres. Of the four spans between five supports, the two through which the stream was flowing are 1.4 metres, and 1.2 metres wide, while the end ones are only 750 millimetres. Length 8.85 metres, width 4.5 metres

There are now no upstanding remains of the bridge. Drill split slabs occur in the river and in the base of the ford and these may be relics of its demolition. The clapper bridge which is reported to have spanned the River Taw 100 metres north of Steeperton Tor Mine has now been completely destroyed. Several large granite slabs line the stream bed serving as a ford for the military track and these may have been robbed from the former bridge. Date of destruction is unknown.
