Former Railway Viaduct at 10 Knockduff Road Jerrettspass Newry BT35 6LU

Three span (originally four span) semi-circular arched squared-stone viaduct [IHR 00231:057] dating from 1862-3 carrying the Newry and Armagh Railway over a river that was formerly dammed to form a mill pond [IHR 00484:003:00(a)], the driveway to No.10 Knockduff Road (the former viaduct is now within private grounds) and formerly over Knockduff Road itself. Located to the W of Jerrettspass, which is approximately 5 miles N of Newry, Co Down, the viaduct is now isolated due to the former railway line no longer being extant. Squared, random-coursed, rock-faced stone walling, parapets and retaining walls. Cut stone voussoirs and coping. From the NE side, the arch on left spans across the driveway and the two arches on right span the dam. A fourth which laterally spanned over Knockduff Road is no longer extant, with only a small section of pier remaining on the opposite side of Knockduff Road. The deck/former railway line is now covered in grass. Materials: rock faced stone Setting: Three arched viaduct is located within the grounds of No.10 Knockduff Road and is accessed via electric gates. Remnant of the fourth arch pier is extant on the N side of Knockduff Road and is abutted by modern stone boundary wall of No. 11 Knockduff Road.
