Campsie Bridge, (Also known as King James' Bridge), Irishtown Road, Omagh, Co. Tyrone, BT78

Campsie Bridge (also known as King James' Bridge) is a two-span humpback road-over-river stone bridge carrying the Irishtown Road over the River Drumragh, built around 1750 and located south of Omagh town centre in County Tyrone. This substantial eighteenth-century structure demonstrates good masonry, robust style and proportionate design.

The bridge is constructed of basalt with squared and tooled spandrels, parapet and V-shaped cutwaters that are carried up to parapet level to serve as pedestrian refuges. On the north elevation, remains of a blocked round-headed flood arch are visible at the right end. The two round-headed arches spring from cement-rendered splayed footings and are constructed with rubble basalt voussoirs. The single carriageway is tarmac with cement-rendered parapets on the carriageway elevation, finished with rock-faced and feather-edged parapet coping and modern cast-iron lamps.

The bridge features grassed and wooded embankments with boundary walls of soldier-coursed rubble basalt coping that extend from the parapets. The boundary wall to the southwest wraps around a three-bay single-storey house with a pitched artificial slate roof, rendered chimneystack, roughcast walls over a rubble plinth, blocked square-headed windows and a door.

The alternative name King James' Bridge derives from historical associations with King James II's retreat through County Tyrone in 1690 following the Battle of the Boyne. According to local tradition, James stayed in Omagh en route to Strabane and crossed this bridge at Irishtown when leaving the town. However, the bridge's current form dates from around the mid-eighteenth century, though it may perpetuate the location of an earlier seventeenth-century crossing. The bridge was listed in the first three editions of the Ordnance Survey Maps (1833, 1854 and 1906) as Campsie Bridge and was noted in the OS Memoirs among the substantial stone bridges in the area.

Significant work has been undertaken on the bridge since a survey photograph from 1970, including the building up of the cutwater into a pedestrian refuge on the north side.
