10th Avenue Lincoln Highway Bridge
Posted July 9, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

It appears that this bridge was rebuilt from a railroad pony truss. The Chicago & North Western reused many older railroad pony trusses of this design as road overpasses. Most of them were extensively rebuilt.
