Colthurst's Bridge is situated 2.9 km (1.8 mi) north of Coachford village in County Cork, Ireland, 3.7 km (2.3 mi) east of Aghabullogue village, and is depicted on both the 1841 and 1901 surveyed OS maps.

The Ordnance Survey name book (c. 1840), refers to it as a bridge with four arches over the Delehinagh River, and named Coulthurst's Bridge, as it was 12 chains (0.24 km (0.15 mi)) south-west of Mr Coulthurst's property.

The Archaeological Inventory of County Cork describes it as a road bridge with three arches, varying in shape and width, but generally semicircular.

The bridge was said to possess dressed sandstone voussoirs, corbels on its piers which supported arch-centring during construction, and low pointed breakwaters on its upstream side.

[1] Pointed arches were an important feature of later Gothic Revival architecture, and said to be also present at Colthurst's Bridge.
