Agivey Bridge, Glenkeen Road, Agadowey, Coleraine, Co Londonderry, BT51

Agivey Bridge is a well-proportioned twin-arched stone and brick road bridge of 1850, carrying the Coleraine to Kilrea road over the Aghadowey River. Although modest in architectural scale, it possesses a degree of embellishment and is notable for the use of brick in its arch soffits rather than stone throughout. It is also of local historical interest as it has an attested designer, builder, and date of erection.

The abutments and piers are constructed of squared basalt blocks brought to courses, while the remainder of the bridge is of roughly-dressed random basalt. At each end of the pier is a curved pointed cutwater rising to arch spring level. The two arches are of segmental profile and equal in size. Although their voussoirs are of roughly-dressed basalt, the soffits are distinctively of brick. A dressed string course wraps around the quoins, runs through the arches at arch spring level, and continues around the tops of the cutwaters. A further string course runs along the base of the parapets. The tops of the parapets have been largely rebuilt in relatively recent times in squared basalt and are coped with roughly-dressed basalt blocks, terminating in out-projecting capped piers.

A plaque on the upstream (north-west) face of the bridge records: "S Gordon / County Surveyor / John Williamson / Builder 1850". The bridge was designed by Stewart Gordon, County Surveyor for Londonderry, and built by John Williamson. The structure is evidently a replacement of a previous bridge shown on the 1831 Ordnance Survey six-inch map, and was undoubtedly financed under the Grand Jury Presentment system. The bridge is explicitly captioned as Articlave Bridge on the 1853 Ordnance Survey map and subsequent editions.

The river bed is pitched with stones and there is a shallow fall on its downstream side. The left bank on the downstream side has also been faced with stones. The bridge lies in open countryside surrounded by trees and fields.
