Cadw's description

Located at the north-western end of Llyn Padarn at the point where it is fed by the Afon Rythallt; the lake and river form the community boundary between Llanberis and Llanddeiniolen.

Shown on the 1838 Tithe Map, the bridge appears to have been built in the early C19 as part of the general road and transport improvements carried out in the Llanberis area during this period.

Bridge. Irregularly coursed and dressed rubblestone with simple coping, slate-slab string course, arch-rings and voussoirs to 4 segmental arches; cutwaters on east side and tapering circular piers to corners.

Included as a substantial and largely unaltered early C19 bridge of strong vernacular character.
