220th Street Overpass
Posted February 24, 2019, by John Marvig (marvigj27 [at] gmail [dot] com)

Looking at Nathan's documentation of this bridge, it appears that this is another example of a railroad bridge reused for a road. There were at least two more examples in the Twin Cities of this along Minneapolis & St. Louis tracks, both which were confirmed to be railroad spans with valuation material. Unfortunately, this is the last survivor of M&StL pony truss overpasses.

On a side note, it is unknown where these came from. There is no record of the railroad ever using these for railroad use anywhere on the system. As a smaller railroad, is it possible they bought the secondhand spans from another railroad?
