Pont Fawr (Llanrwst Bridge) (Partly in the Community of Trefriw)

Pont Fawr, also known as Llanrwst Bridge, is a steeply ramped stone road bridge dating from 1636. It features three segmental arches, with the central arch spanning approximately 18 metres and the outer arches around 13.5 metres each. Cutwaters on either side rise to create refuges in the parapet. The bridge is constructed from coursed local gritstone and slate rubble, with the arch voussoirs set slightly back. The masonry of the west arch is made from smaller blocks.

The parapet is topped with heavy chamfered coping stones secured with iron cramps, and the approach walls flare outward. On the south side of the central arch, the parapet displays a stone relief of the Stuart Arms, along with the initials 'CR', framed by fluted columns that support a floral entablature and ogee cresting. Below the arms is the date '1636'. A sundial was added above to commemorate the bridge's tercentenary.

The north parapet mirrors this design, featuring the Prince of Wales feathers emerging from a crown, flanked by the initials 'CP', and similarly framed by columns and ogee cresting, topped with weathered relief pinnacles. The inner parapet also shows the date '1636', and includes carriage stones to protect the masonry. Additionally, the stone on the inner south parapet above the rebuilt west arch bears the initials 'TR'. The bridge has a tarmacadam carriageway surface.
