I didn't like steel bridges until I built this one. I felt a wooden bridge would block too much of the view of the canyon behind and below the bridge so the more open look of a steel trestle was needed. I based this bridge on Micro Engineering's beautiful Tall Viaduct kit, cutting and pasting as necessary to fit the space. The only mistake I made was in trying to have a turnout on the bridge. Some advice: DO NOT DO THIS. Actually, I could see placing a turnout on a bridge if you made the bridge out of brass so alignment could be strictly maintained.
