Historical information

The bridge first appears on the second edition OS map of 1853 (railway lines have been added to a revision of this edition available at PRONI). The railway is captioned ‘Portadown, Dungannon and Omagh Railway’. By the third edition of 1906 the railway is captioned ‘GNR (Portadown and Londonderry Branch)’ and by the fourth edition ‘GNR (Ireland)’.

McCutcheon comments on the development of the railway, “…in November 1856, the directors of the Portadown &Dungannon Railway Company…sought authority to extend their line to Omagh and lease it to the Ulster Railway Company. In August 1857 Royal Assent was given to a bill incorporating the Portadown, Dungannon and Omagh Junction Railway Company and the 27 miles of single-track line from Dungannon to Omagh were built with £100,000 of share capital and £33,000 of loans…the company was compelled to drive a tunnel of single-track width almost half a mile in length, through Windmill Hill, before the railway could be brought up to Dungannon. Despite the substantial engineering involved, within three years the line had been pushed across the windswept moorlands of the south Sperrrins by Pomeroy and Carrickmore to Sixmilecross, Beragh and Omagh, where a junction was made with the Londonderry & Enniskillen Railway on 2 September 1861. On completion, the 41 miles of single-track way from Portadown to Omagh were leased to the Ulster Railway Company for 999 years at a minimum rate of £10,000 per annnum and participation in surplus receipts over £23,000 per annum – a figure exceeded in almost every year of operation.” (p.107)

The line was taken over by the Ulster Railway company on 1 January 1876 and this merged with the Northern Railway Company on 1 April 1876 to form a new company called ‘The Great Northern Railway Company (Ireland)’. (p.111)

Evaluation

A single-span road bridge, built c.1850, carrying Tiroony Road over railway line (now disused). Stonework detailing and dressings have survived and the structure remains unaltered. However, with the removal of the railway its significance is much reduced and there are other, better examples listed.
