Three tier travel
Recently, I blogged about walking in Crumlin Glen. The car park is close to this unusual triple level bridge. It is a railway bridge over a road bridge, over a river, where a boat, a train, a car and even a plane could, theoretically cross paths. I did see cars on the road as I walked across the road bridge on my way to and from the town.
First built in 1871 the original railway span was a powerful wooden structure. The old bridge was replaced by a new one around 1908. The Bailey-Bridge type appearance was then replaced by the modern steel viaduct extending high and wide for greater strength. The Antrim railway line runs for 18.5 miles with 44 bridges.
