Bridge, Cannyreagh Road, Hogstown, Donaghadee, Co Down

This is a single-span, humped-back road bridge, constructed around 1859-60, built to carry the Cannyreagh Road over what was the Newtownards-Donaghadee section of the Belfast & Co Down Railway. The railway line has since been removed, and the former cutting to the east has been largely filled in, obscuring that side of the bridge. The bridge is situated on a bend in the road, approximately half a mile west of Donaghadee.

The bridge is largely constructed of rock-faced fieldstone rubble, featuring a single elliptical arch. The arch itself is lined with brick on the intrados, and utilizes rock-faced, v-jointed sandstone for the voussoirs and quoins. Splayed triangular buttresses are positioned on either side of the arch on the western face of the bridge. Sandstone string courses run at arch springing level and just above the arch, with the upper course visible only from the west due to the infill of the former railway cutting. The parapets are finished with sandstone coping.

The bridge was built between October 1859 and June 1861 as part of the Belfast & Co Down Railway's new line between Newtownards and Donaghadee. It was likely designed by Sir John MacNeill, the BCDR’s chief engineer, and constructed by his principal contractor, Patrick Moore. The railway line closed in 1950. The structure has industrial archaeological interest.
