The Kilnap Viaduct (known colloquially as the Eight-Arch Bridge) is an eight-arch railway viaduct located in Cork, Ireland. Built in 1845, it carried the Great Southern & Western Railway line to Cork over the valley of Glennamought River and Mallow Road.[1] The viaduct is listed as a protected structure by Cork City Council.[2]
The eight-arch railway viaduct features rock-faced ashlar limestone piers with a cut stone impost supporting squared coursed limestone spandrels with dressed limestone string course. It has rock-faced limestone voussoirs leading to round-headed arches, ashlar limestone vaults to barrels and a squared coursed limestone parapet with cut stone coping.[1] The viaduct was built by William Dargan.[3]
As built, it was 420 ft long and 90 ft high.[4]
Further south is the Kilnap viaduct shown under construction by Dargan in 1849. It is still in use today, as is the 8-arched viaduct at Monard near Rathpeacon outside Cork.
