Todd's Bridge, Todds Road, Omagh, Co Tyrone, BT78 5PL

Todd's Bridge is a single-span road bridge built around 1850, carrying Todds Road over what is now a disused railway line near Omagh in County Tyrone. The bridge was constructed to carry the road over the newly built section of the Londonderry to Enniskillen Railway.

The structure is built in squared-and-snecked rockfaced sandstone throughout. It features substantial piers and abutments of the same material, with rockfaced spandrels and a parapet that terminates in large piers on either side. A plain sandstone string course runs at carriageway level, and the parapet is finished with rockfaced coping. The arch itself is elliptical-headed with dressed rockfaced voussoirs, and the carriageway is approximately 4 metres wide.

The bridge is largely buried beneath agricultural land that now fills the original railway cutting. Hedging bounds the land to the east and west of the road.

The bridge was first recorded on the second edition Ordnance Survey map of 1854. It was built during a period of significant railway expansion in the region. The Londonderry and Enniskillen Railway Company, formed in 1845, constructed a single-track line extending southward from Londonderry. The line reached Strabane by April 1847, Omagh in 1852, Fintona in 1853, and Enniskillen in 1854. These connections brought substantial commercial advantages to the towns served, establishing Omagh and Strabane as major market centres from which goods and livestock could be conveyed northward to the port of Londonderry. By 1861, the railway provided direct communication between Dublin, Belfast and Londonderry. In 1860 the line was leased to the Dundalk and Enniskillen Railway Company, later becoming the Irish North Western Railway Company. In 1876 this merged with other companies to form the Great Northern Railway Company (Ireland), under which name it appears on the third edition Ordnance Survey map of 1905.

Although the bridge has been partially buried and is largely overgrown, the stonework detailing and dressings have survived and the structure remains relatively intact. It is one of a series of bridges that remain as a reminder of the railway's former route and part of the industrial heritage of the district. However, its setting and function have been compromised, and other examples of similar bridges from this railway remain in better condition.
