Nearby was the Roman settlement of Canovium at Caerhun, and was the site of a Roman river-crossing point of the River Conwy.
The mediæval ferry, which operated from 1301, was replaced by a steel bridge of rivetted plates and angles on piers of concrete and masonry in 1897. The present bridge dates from 1977-8 as the original got seriously rusty. The pre-fabricated steel sections are hot-dip galvanised for protection against corrosion, and no part is too heavy for two men to carry. The piers of the old bridge were in perfect condition, and it was a stipulation that the footway be available for use at all times during reconstruction. It was therefore decided to adopt an unusual installation method, whereby the new bridge was assembled through and around the old bridge.
Once completed, the new bridge was lowered onto the piers by cutting away piece-by-piece the old bridge. The bridge also carries water in a pipe from Llyn Dulyn and Llyn Melynllyn in the Carneddau mountains to the coastal town of Llandudno.
