Road Bridge, Bridge Road, Helen's Bay, Bangor, Co Down

A single-arch masonry bridge, built c.1853 to designs by Benjamin Ferrey to carry the two lanes of traffic and a footpath of Bridge Road over Clandeboye Avenue. The abutments are of quarried rubble blackstone brought to courses. The arch is of two-centred profile with an ornate moulded sandstone voussoir. Around the extrados of the latter is a course of square sandstone blocks. The arch soffit is of ribbed ashlar sandstone. Surmounting the crown on both faces is a square sandstone plaque bearing the date 1853 in bass relief. The spandrels are of rubble blackstone with a narrow moulded sandstone string course over. The parapets are detailed as the spandrels and are coped with dressed sandstone blocks, the top faces of which slant down towards their road face. They end in canted terminal piers over geometric corbels rising from arch spring level. Both the piers and corbels are of ashlar sandstone. The parapet string course delineates the base of each terminal pier. The wing walls are of random rubble blackstone Setting Located in Helen's Bay to the north of the railway station (HB23/15/039A) and carrying the Bridge Road over Clandeboye Avenue.
