Knox County Road 013 Bridge
Posted September 10, 2020, by John Marvig (marvigj27 [at] gmail [dot] com)

I would love to know more about this one. My 1937 records indicate this bridge was a 30' iron girder, as does a 1950 track profile. There was a 75' pony truss to the west on Route P, but that is gone, and this truss is much smaller.. Also, looks likely that it is a recycled railroad span.
