Recycling rail cars as bridges

Paragon Bridgeworks  recycles railroad freight cars and flat beds and turns them into bridges! Different spans are 20, 40, 55, 60, and 89 ft lengths, and they are totally safe. Website is www.paragonbridgeworks.com

Looked at a property before we bought this place where a guy had taken an old flatbed trailer like a Mack truck would haul and made a bridge. I also know a guy who used a mobile home frame to build one. I have been thinking of a similar project because my pond is longer than wide and we got a spot about 35' in the middle where it is narrowest that a bridge would be a good addition.
