The Pillars of Monaghan

Prehistoric or post-industrial?

Originally constructed as a timber truss bridge this viaduct carried the Dundalk and Enniskillen Railway (later Great Northern Railway of Ireland) on the approaches to the River Finn crossing. It was later replaced by lattice girder spans on braced metal trestles and then in c1925 it was replaced again by steel plate girder spans on cylindrical piers. On closure in 1959 the deck and much of the metal casing from the piers was removed, just leaving the pillars with one cross beam as a monument to the railway.
