If you are interested in railway artefacts, then take a look at the Bleach Green viaducts, the station here closed in 1977 but as the name implies its history stems back to the linen industry when surrounding fields would have been used to dry the freshly bleached linen. A siding ran off from the Belfast/Larne mainline to Hendersons Mill and the bleachery. To see the viaducts, continue along the Causeway Coastal Route from the large roundabout, go through the next roundabout then lookout for a set of traffic lights and on the left-hand side Whiteabbey Presbyterian Church Hall, turn left and drive up Glenava Manor beside it, you can park at the top and then walk. The impressive viaducts are 70 feet high with a span of 600 feet, built of precast concrete in the 1930s, they are unique examples of this type of structure. It does look a little bleak and uncared for up there but worth the walk if you are interested in this subject.
