Crumlin Viaduct (Northern Ireland)
From Wikipedia, the free encyclopedia

The Crumlin Viaduct is a railway bridge in Crumlin, County Antrim. It has the distinction of being the only place in Ireland where a train, plane, car, and boat can theoretically cross paths, due to its unique status of being a railway bridge straddling a road bridge across a river, with Belfast International Airport two kilometres to the north.[1]
The railway line through Crumlin opened in 1871, crossing the Crumlin River by means of a simple lattice girder bridge. This was replaced in 1915 with the current structure, a Pratt truss. The original was reused at Adelaide railway station in Belfast.[2] The current viaduct was designed and built by James Findlay & Co. of Motherwell, Scotland.
Passenger traffic ceased in 1960.
The bridge was reinforced in the early 1970s[3] to prepare for the reintroduction of passenger traffic, in 1974. It then carried trains between Derry, Antrim, Lisburn and Belfast until 2003, when the passenger service ceased once again.
