I went exploring the other night just before sunset and ended up at this old, abandoned bridge over the Mackinaw River near Tremont. I love the way the rusty steel beams seem to glow in the evening twilight. As old as the bridge looks, it’s actually only been closed for a few years. It has a steel structure, but the deck is made of wooden planks about four inches thick. I can remember driving over it not too long before it was closed, but now I’m cautious even walking across.
