Knockan Bridge, Killunaght Road, Dungiven, Co Londonderry

Knockan Bridge is a substantial late 18th-century, humped four-arch rubble sandstone bridge situated on the Owenbeg River in the Knockan townland, close to Gallany. The bridge carries the Killunaght Road and is set within a picturesque environment, forming a pleasing group with Knockan and Ashpark houses and the Old Feeny Road, which is characterised by mature trees.

The bridge’s construction utilizes sandstone random rubble with almost semi-circular arches. The two central arches span approximately 4½ metres, while the outer arches span 4 metres. The arches rise from low supporting walls, featuring neatly cut voissoirs. Breakwaters in a triangular form are present on the upstream and downstream sides, and a band of concrete apron has been applied to each. The soffits of the arches are finished with rough rubble and mortar daubing. The carriageway is slightly humped, measuring 6½ metres wide, expanding to 8 metres at either end. A 60-metre-long parapet wall is present, with a concrete coping of hogsback profile which obscures the original vertical stone coping. A wrought iron field gate stands at the eastern end, supported by stone piers with flat pyramidal caps.

The use of semi-circular arches suggests a construction date within the late 18th century, likely built under the Grand Jury system. Historical records, including Ordnance Survey Memoirs, describe the bridge as "neat" and constructed of "cut freestone." It once served as the main road between Dungiven and Derry prior to the construction of an alternative route via Foreglen. Objections to the bridge's construction were raised at the time by Messrs Hunter of Drumovit House and Brown of Comber House, as they feared it would divert traffic away from Feeny and Claudy. The bridge possesses industrial archaeological interest due to its historical context and the construction methods employed.
