Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is barely old enough to be considered for HistoricBridges.org. This relatively plain structure is made interesting by way of its unusual arch shape/configuration and the dramatic landscape around it including a rock cliff and small waterfall. The older and more historically significant truss bridge is where the few photos HistoricBridges.org has of this bridge were taken. The Hogback name refers to the limestone rock cliff, which was cut through in the 1940s to create a channelized concrete drain that diverted the original route of the flood-prone Dry Run which originally ran through Decorah.
