On 21st January in either 1412 or 1413, Bishop Stafford granted an indulgence in favour of Treverbyn Bridge, the condition of which was described as “threatening total ruin”. So the medieval bridge at Treverbyn is likely to consist of parts of an earlier structure.
Indeed, the western approach span, which measures 2.7m, is probably part of the older bridge. There are two other spans, pointed in design and also constructed in stone. These date from 1412/1413 and measure 7.3m.
The bridge is 2.6m wide between its stone parapets, with refuges formed by the extension of the triangular cutwaters below to the level of the carriageway above. A cutwaters is a projection from a bridge pier to form a sharp angle in the direction of the water flow, with the idea of deflecting some of the power of a river in spate.
Treverbyn Ancient Bridge was part of the main route from Bodmin to Liskeard through St Neot for many hundreds of years, until a new bridge was constructed immediately downstream in 1929. It is used now as a footbridge.
