Treverbyn Bridge

Treverbyn Bridge is a three-span bridge that dates from the early medieval period and was substantially rebuilt around 1412. It was widened in the 18th century and closed to motor traffic in 1929.

The bridge spans the River Fowey from east to west, measuring about 22 meters long and 2.5 meters wide. It is primarily constructed of slatestone rubble, with some granite boulders and slabs, particularly at the western arch. At the eastern end, there are two four-centred arches with recessed arch rings, flanking a central pier that features triangular cutwaters, which continue into the parapet as refuges. A slate string course runs along the base of the parapet on the downstream side.

The earlier western arch has an inner rounded slatestone arch and is flat-topped with a granite slab. The parapet is carried over at an angle on a second granite slab. The pier between the eastern and earlier western sections of the bridge is wider, with unequal cutwaters and no refuges on both the upstream and downstream sides. This area is where the river divides due to an island on the downstream side. The abutments and parapet are largely made of local slatestone, with some granite from earlier re-used material. The parapets are approximately 50 centimeters high and are capped with iron-cramped dressed granite coping slabs. The parapet at the western end splays and curves to the downstream side as a result of the widening in the 18th century.
