I’ve been sifting through some photos I took back in 1996 when I was at Glasgow School of Art. They came out of a project I was doing related to the Antonine Wall, the Roman construction which spanned the Forth-Clyde isthmus. I made a series of cycle trips to locations along the wall. The sequence of photos I’m presenting here are of the Erskine Bridge, which crosses the Clyde near the western end of the Antonine Wall, within sight of the fort at Old Kilpatrick. Suspension bridges have been another of my obsessions. There is somehow a connection between the miraculously thin concrete span of the bridge and the Antonine Wall, which was also a structure extruded beyond what one would think possible.
