Bridge, Ravernet Road, Lisburn, Co Antrim, BT 27

This slightly skewed masonry arch bridge carries the Ravernet Road over the river of the same name. It is of random rubble construction throughout with embellishments in granite. The latter takes the form of rock-faced and margined granite blocks to the abutment quoins, segmental arch voussoirs and parapet ends. There is also a plain granite platband through the arch at spring level. The parapet is coped with chamfered granite blocks (dislodged at the S end of the W parapet). The deck carries a 1½ lane road over the river. The bed of the river under the arch is pitched with stones to prevent undercutting of the abutments. A pipe is carried across the upstream (E) face on steel brackets bolted to the face of the bridge. At the NE end of the bridge, concrete steps lead down to the right bank to facilitate access to a water gauging station a short distance upstream.
