Trekelland Bridge

Trekelland Bridge is a road bridge dating from the late 15th century or early 16th century, with later alterations. It is constructed of granite ashlar, featuring later stone rubble parapets and abutments.

The bridge consists of two main arches and a smaller flood arch at the south-west end. The arches are four-centred and designed in the Perpendicular style. Each of the main arches has a span of 5.8 meters, while the flood arch measures 2.6 meters wide. Each arch features a single arch-ring made of granite voussoirs. In the main arches, these voussoirs are slightly recessed below a hollow-chamfered granite string-course, whereas in the flood arch, they are flush with the bridge sides and lack a string course. A similar string-course marks the impost line where each arch springs from the piers and abutments. The piers are equipped with pointed cutwaters at each end. The arch vaults, piers, sides, and abutments are mostly faced with neatly dressed ashlar granite slabs. In contrast, the causeway sides are faced with local metamorphic stone, suggesting a later date for this facing.

Above the arches and across the piers, a granite string-course extends 20.75 meters from abutment to abutment, emphasizing the distinction between the granite-faced bridge below and the parapets above. The parapets, made of local stone like the causeways, feature chamfered granite coping, some of which still retains iron cramps.

The triangular cutwaters of the piers rise into the parapets as refuges on each side, also made of local stone but with granite quoins along part or all of each apex. The parapets above the string-course and carriageway level have been rebuilt at various times from the post-medieval period to modern times, using slate rubble and reused chamfered granite coping.
