This bridge has a builders plate that gives a build date of 1898. The Frisco was certainly operating through this route in 1898, however the piers have an inscribed date of 1928. The question is whether this bridge was moved here from another location in 1928, or if the concrete piers were built to upgrade and reuse the bridge that was already here. With a build date of 1898, this would make this the oldest truss bridge in Crawford county still open.

Took a walk out there this afternoon. My (amateur) opinion is that this bridge was built for this site, but was raised about two feet in 1928. The cut stone footing at the south end has a poured concrete filler on top of it, supporting the through girder span. Fresh heavy limestone riprap is evidence of a long-fought battle with flood waters at this site. In the surrounding woods there are piles of flood debris all the way to track level. Thanks to Gene and all the others here. I've ridden through this bridge several times, but never noticed what an interesting site it is.
