WASHINGTON STREET BRIDGE OVER THE GREAT MIAMI RIVER
City of Dayton, Ohio
The historic Washington Street Bridge is a seven-span, earth-filled, concrete-arch bridge supported by half-height wall-type piers and full-height abutments. Constructed between 1905 and 1906, the bridge arches gracefully over the Great Miami River in concert with the numerous other arched bridges located along Dayton’s five rivers. For this reason, a design aesthetic reflecting an arched shape was a top priority for the proposed structure. Woolpert provided the preliminary development and detailed final design for this bridge’s replacement.
Woolpert’s preliminary study focused on four different bridge types and various aesthetic upgrades. The study included preliminary drawings, renderings, and detailed descriptions of the alternates and upgrades, along with complete cost estimates for each. Each of the studied concepts was different, examining different structural systems, pier details, architectural light fixtures and railing types. Woolpert’s broad approach to concept design provided the City of Dayton with multiple opportunities to tailor the bridge design to best meet its aesthetic and functional needs.
