Dunadry Bridge, Straidballymorris, Dunadry, Co. Antrim, BT41 2RY

Dunadry Bridge is a dignified nineteenth-century stone bridge built between 1820 and 1839, carrying the Belfast Road (A6) over the Six Mile Water. This three-span road bridge, with a slight skew, replaced an earlier structure depicted on the 1834 Ordnance Survey map, which may have consisted of five shorter spans. The bridge reflects the engineering advances of the nineteenth century. The piers, spandrels, and parapet are constructed of coursed black stone, with a chamfered stringcourse at carriageway level. The segmental arches are dressed stone voussoirs, as is the parapet coping, and there are V-shaped cutwaters on both the north and south pier elevations. The bridge is described in the OS memoirs as a "plain but handsome skew bridge of 3 circular-segment arches." The bridge appears on Ordnance Survey maps from 1834 onwards. The bridge has woodland wetlands to the south embankments and to the northeast, and modern housing to the northwest. It is of industrial archaeological interest and has local historical significance.
