Description 

The history of the East Washington Avenue Bridge is consequential in two areas. As a bridge it represents an early phase in the evolution of Strauss Bascule Bridge Company designs and embodies two of Joseph Strauss' major patents. It has transitional aspects, electrically operated but possessing a complete, manually operated mechanical backup system and a manually operated auxiliary brake. Secondarily, the bridge site and surrounding neighborhood were the location of industries that developed and expanded the innovative production technology known as the "American System of Manufacturing." The bridge served a dynamic historic industrial neighborhood in an era when United States firms rose to a dominant position in world markets.

East Washington Avenue Bridge
Posted July 16, 2014, by Nathan Holth (webmaster [at] historicbridges [dot] org)

For reasons that elude me, the SHPO agreed that the work done on this bridge in 1998 was a "rehabilitation" although I would disagree. The entire superstructure was demolished and replaced (and note the UGLY modern railings that replaced the originals), and the approach spans were reconfigured. They did maintain the operational design of the bridge meaning it still operates to a Strauss design meaning you have a second trunnion for the counterweight... which is interesting since it was a style that hadn't been built for 60 years... so as a replica of a mechanical design its interesting, but I have trouble calling it rehabiliation... or even replication given that things like railings, rivets, etc, would not be found on the bridge today.
