Cadw's description

In the grounds of Plas Tregayan and carrying the main driveway towards Lower Lodge; spanning the Afon Erddreiniog c450m ESE of the house.

C19, probably contemporary with the development of the adjacent house and estate buildings; built for Admiral Lloyd, the owner and occupier in the Tithe Apportionment of 1839.

Small roadbridge of a single span; voussoir arch with slightly advanced keystone. Low parapet wall of rubble masonry.

Included as a good C19 roadbridge which forms an important component part of the estate at Plas Tregayan. Built to a coherent design and echoing the C19 character of the house for which it was built; a reflection of the expanding fortunes of the estate at that time.
