Railway Viaduct (2), Bleach Green Junction, Newtownabbey, Co Antrim, BT37

A seven-arch concrete viaduct carries the Belfast-Larne railway over the Three Mile Water (here known as Valentine's Glen). It is of painted reinforced-concrete throughout, all cast in situ. The arches are of segmental profile and embellished with a banded reveal over (which signifies the depth of the arch cast). The middle arch spans the actual river and is wider than the others, all of which are of equal width. It has hollow spandrels, with two vertical slabs connecting its extrados on either side of the crown with the underside of the deck. This arch is also flanked to each side with a pilaster which continues up to parapet level as a pedestrian refuge. Cantilevered refuges also project from the face of each parapet over the remaining piers. The parapets have been cast with vertically fluted panels along their outside faces. A slightly advanced string course also runs along their base and they terminate at both ends in advanced piers. The actual viaduct is c.120m long but its south end continues for a further 100m under the south most three arches of viaduct HB21/10/001A. A modern footbridge also now crosses the river through the middle arch.
