Future uncertain. Plans were to build a new bridge for vehicular use on new alignment and preserve historic bridge for non-motorized traffic, but locals want a rehab for continued vehicular use and do not want any new bridge.
Built 1935; rehabilitated 1964
Pin-connected Parker through truss main span, and a Warren pony truss approach span.
Length of largest span: 180.1 ft.
Total length: 346.1 ft.

Montana gives bridges two ratings, one based on the health of the bridge and one based on sufficiency of the bridge. Health wise this bridge outscored the rest of the bridges in the state at 96.49. But then came in at 43.2 in sufficiency just because its one lane, and has a weight limit. And now the state is wanting to bypass or replace it. I hope the community there fights to keep the bridge standing at the very least.

This bridge is NBI listed as 1935, but I am thinking the main pin-connected thru truss span is older and was relocated here. The pony truss might be from 1935 however.
