Description
Trewornan Bridge is a road bridge over the River Amble and its flood plain, built in 1791 by Reverend William Sandys. The structure is made of stone rubble and features dressed stone pointed arches along with moulded granite strings, reflecting a medieval design. It has four pointed arches with spans ranging from 5 to 6.5 metres and five cutwaters on each side. The stone rubble parapets extend over the cutwaters to create refuges. The bridge has been noted by Henderson as the only Cornish post-Reformation bridge worth visiting. It was previously listed twice under the parish of St. Minver Highlands, but that entry was removed from the List on 19 October 2017. This entry underwent a Minor Amendment on the same date.
