Description 

This bridge was apparently washed out by a flash flood, but the wreckage now sits on the bank. One truss is intact, while the second truss is broken apart - but most or all of the parts are still present. Estimated length is 60-70 feet. The bridge has very lightweight members with no V-lacing.

Looking at the I-beams and the bolts this seems to be a fairly late design. Lacing was probably a thing of the past when this was built. The I-beams are stronger than built-up, laced pieces.
