Notes
  • Significance: The Mahoning Avenue Pratt Double Deck Bridge was built in 1903 by Huston and Cleveland of Columbus, Ohio. The upper level - a Pratt deck truss - spans the whole of the Mill Creek Valley, while the lower level is an adapted form of the Pratt through truss and only spans Mill Creek. The bridge is double decked at this point and is the only known example of a Pratt Double Deck Bridge in Ohio. The bridge is listed as a "selected bridge" in the Ohio Department of Transportation's Ohio Historic Bridge Inventory Evaluation and Preservation Plan.
