Muckamore Bridge, Oldstone Road, Muckamore, Antrim, Co Antrim

Muckamore Bridge is a late 18th-century masonry bridge carrying the main road over the Six Mile Water. It is constructed as a five-arched structure built mainly of blackstone rubble with rough stone voussoirs to segmental arches, rubble vaults, and piers faced with triangular cutwaters of similar rubble. The bridge has been widened partly in brickwork, introducing variety to the original composition and consequently displaying the use of basalt rubble, quarry dressed basalt, and brickwork construction in the one structure.

On the west face, the spandrels and parapet are of basalt rubble set in the same plane, though the top of the parapet has been newly rebuilt. On the east face, the spandrels of the southern arches are set back slightly below the parapet, all of basalt rubble. The northern arches on the upstream side have been rebuilt with brick voussoirs and vaults, and their piers are faced with lower triangular cutwaters of coursed basalt. The spandrels of these rebuilt northern arches are flush with the parapet, and all stonework of the northern portion is of quarry dressed basalt, with the parapet capped in cement render. The carriageway is flat, with a raised footpath on the west side.

The precise date of the bridge is not known, though it appears on the Ordnance Survey map of 1832. The Ordnance Survey memoirs of the 1830s noted that the bridge "appears to be of later date" than the Massereene bridge built in 1708. The memoirs also referred to it as Moylinny Bridge, describing it as "a clumsy old structure but in a tolerably sound state" measuring 94 feet in length and 22 feet in width. The precise date of the widening in brickwork is not known but appears to be mid-to-late 19th-century work.

The bridge stands in a largely unspoiled condition in a rural area currently being developed with housing adjacent to the south end on the west side. The bank on the east side at the south end is comparatively flat grass, while the bank on the west side has been rebuilt with basalt rocks. At the north end both banks are steep, with mature trees and thick bushes. At the north end the parapets extend to abut an adjacent railway bridge, with which it forms part of an interesting architectural group.
