  1. Aesthetic Enhancements Through the Community Workshop Process Fifth Street over the Great Miami RiverDayton, Ohio Presentation By: Jeffrey L. Griffin, PE Burgess & Niple, Inc.

  2. Project Location

  3. Site Description • Fifth Street Bridge connects downtown Dayton to the historic Wright Dunbar area, home of the Wright Brothers and poet Paul Laurence Dunbar. • The bridge carries approximately 15,000 vehicles per day and significant pedestrian traffic from the adjacent Sinclair Community College campus. • The bridge is a vital and highly visible transportation link for the city.

  4. Looking east, towards downtown Dayton Former Bridge - Site Photographs Looking west, towards Wright-Dunbar district

  5. Former Bridge • The former Fifth Street Bridge was a closed spandrel - filled arch structure constructed in 1916. • The bridge consisted of seven spans and was approximately 620 feet in length. • It was owned and maintained by the Ohio Department of Transportation (ODOT).

  7. New Bridge Appearance • ODOT Scope of Services – “Aesthetic values will be incorporated in the design. Possibilities include lighting, color, texture, and patterns” • Funding for aesthetic enhancements was limited • Build bridge desired by community with money ODOT was willing to spend ($7.3 million)

  8. Process for Determining Aesthetic Enhancements • Conduct Opinion Leader interviews • Determine potential aesthetic opportunities, based on interviews • Conduct workshop with community leaders to discuss design preferences for new bridge • Develop renderings based on workshop input • Conduct second workshop to finalize aesthetic enhancements • Develop design based on second workshop input

  9. Opinion Leader Interviews • Question: “What does the community want to see after the new bridge is built?” • City of Dayton, Sinclair Community College, and Dayton Chamber of Commerce were interviewed, among others. • Answer: “Give us an arched bridge.”

  10. Potential Aesthetic Opportunities • Other Great Miami River bridges in Dayton • Architectural influences in downtown area • Modern, Victorian, Classical, and Art Deco exist in close proximity to bridge • Architectural style impacts railing, lighting, and concrete color and texture

  16. Architectural Influences - Classical

  17. Workshop #1 – Determine Design Preferences • Describe scope of project • Display images of project area (both bridges and architectural styles of buildings) • Present examples of aesthetically-enhanced railing, lighting, and concrete color/texture from other bridges • Reach consensus on style (classical and art deco were preferred) • Ten different agencies were represented at Workshop #1

  18. Develop Renderings Based on Workshop #1 Input • Criteria • Unique • Conventional materials • Construction “friendly” • Cost effective • Previous experience aesthetic detail development • Numerous iterations/debates/arguments • B&N team included an architect, a graphic artist, bridge engineers, and other interested observers • Still friends afterward

  19. Classical Styling

  20. Art Deco Styling

  21. Similarities Between Classical and Art Deco • Both used conventional concrete I-beam interior beams with spliced haunched fascia girders for arched bridge appearance • Both utilized conventional materials and construction methods • Both met ODOT cost objectives for project

  22. Workshop #2 – Finalize Aesthetic Enhancements • Renderings presented for classical and art deco styling • Recorded comments and preference from each workshop participant • Both received positive comments from nearly everyone • Art deco most preferred • Community grateful for opportunity to participate in design process

  28. Construction Costs • Construction of the Fifth Street Bridge was completed in 2003. • The total construction cost for the project was approximately $6.7 million. • The cost of the new bridge alone (not including removal of the existing bridge) was $5.4 million, or $97 per square foot of bridge deck. • The cost of the bridge superstructure was $3.0 million, or $54 per square foot of bridge deck.

  29. Design Awards – PCI 2004 Design Award, 2004 PCA Bridge Design Award of Excellence
