History

Probably late C18 or early C19 road bridge. Merioneth was the last of the Welsh counties to have turnpike roads and it was at a county meeting in Dolgellau in 1775 that it was resolved to convert the principal tracks of the county into turnpikes, in partnership with Caernarfonshire. By the end of the C18 most of the existing roads had been brought under the Trust under the Merioneth Turnpike Act of 1777. What is now the A496 was constructed following the reclaimation of Traeth Mawr, and the erection of the Cob at Porthmadog, which opened in 1808. It replaced the former county road between Harlech and Maentwrog which had followed an old packhorse route crossing the adjacent Ivy Bridge.

Exterior

Large road bridge built of coursed masonry including long blocks of slate. A single segmental arch with dripcourse and flanking pilasters; low parapet, also with dripcourse and raking stone slab coping.
