you've got a cool thread going here. Lots of old buildings, places, train stuff, and bridges. All things I like to discover when I'm out for a ride. You have a lot of photo's of old bridges like the one below. Did they use to be train related? I noticed many have lengthwise planks and couldn't help wonder if these replaced old rails or are they just placed for auto traffic. Thanks for sharing and keep it going, good stuff!
