The bridge is probably of the mid C19, and probably constructed to serve the quarries which opened at Moelfre in the 1860s.


The bridge is constructed with local rubble stonework and comprises two segmental arches spanning approximately 5.6m on to a central rough stone cutwater, each arch of shaped rubble voussoirs rising 2.6m and set flush with the spandrels. A string course carries the slightly outset parapet of thin slate, perhaps a rebuilding. The road width is 2.83m between 48cm parapets.
