This interactive span is based on the Howe Truss bridge near Carcross, Yukon Territory
on the White Pass & Yukon Railroad. Wooden moveable bridges were rare. Narrow gauge ones were even rarer. This is
rarer yet in that the tracks are offset from the centerline of the bridge to make room for a pedestrian walkway. No
info was available on the approaches so I used 100 ft trestle sections with an added walkway.
