Sadly, this bridge is in bad shape and unsafe to cross. See photos of deck. The highway department has it blocked off.

Did a little looking into this bridge. See the attached link for some information, although this article is from 2002.

I think the information of original build date of 1921 is incorrect. The original Yellowstone River Bridge, at Fallon, that was destroyed by ice in 1943 had four spans, three of which went into the river. I think the remaining span was moved to this location.

I looked through Jon Axline's book, 'Conveniences Sorely Needed', for information on the original bridge at Fallon, but it give no information on part of it being reused.

Any thoughts on this?

Bridge is actually a Pennsylvania truss and was probably relocated to its current place in 1946.
