Glenkeen Bridge, Boleran Rd, Ringsend, Coleraine, Co Londonderry, BT51

A three-arched stone road bridge, likely dating to the late 18th or early 19th century, carries the Garvagh – Limavady road over the Mettican River. The bridge is constructed of random rubble blackstone throughout. The arches are segmental in profile, with the central arch being slightly higher, creating a gentle curve in the bridge deck. Angled cutwaters are located on the upstream and downstream ends of the piers, rising to arch spring level. The right-bank (north) arch is normally dry. The parapets have likely been rebuilt and are now coped with concrete; the north end of the west parapet has been rebuilt more recently. A modern steel nameplate identifying the bridge and river is affixed to the upstream parapet. Damage to the west wall of the approach road from the south has occurred due to a vehicular impact.

The bridge appears on an 1832 Ordnance Survey map and is described in the 1836 Ordnance Survey Memoir for Errigal Parish, which records spans of 10ft 6in, 10ft 6in, and 9ft 4in, a road width of 18ft 6in, and parapets 4ft 6in high, all in good repair. It was subsequently named Glenkeen Bridge on the 1853 Ordnance Survey map and later editions. These dimensions correspond with the current dimensions of the bridge. An uncaptioned bridge is shown at this location on the 1832 Ordnance Survey map. The bridge is situated in a rural setting, surrounded by fields. While noting no special architectural or historical interest, the bridge is considered to have some industrial archaeological interest.
