The historic Stewart Street bridge spans the Great Miami River and is a main thoroughfare from I-75 to both downtown Dayton and the University of Dayton. It is also the main connector, both for vehicular and pedestrian traffic, between the main university campus and the sports complex that houses UD Arena as well as the stadium and softball/baseball diamonds. The existing structure was a 42-foot-wide, four-lane arch bridge built in 1911 with 6.5-foot sidewalks on both sides. Woolpert prepared a preliminary study for multiple options under several alternatives: no build, major rehabilitation, basic or enhanced replacement and new or enhanced bridge on new alignment. A public involvement meeting was held to present aesthetic structural, rail, lighting and overlook features.
The project included detailed agency coordination with several city departments and organizations and was aligned with NEPA and the Historic Eligible Bridge replacement process. The final proposed design was a 72-foot-wide, six-lane replacement bridge with 10.5-foot sidewalks, including a rail system, for a total width of 93 feet. Not only was the project schedule met, but the bridge improved traffic flow and pedestrian safety.
