Public-private funding partnership makes project a reality

When a community undertakes a historic preservation project, it can be difficult to quantify its total value to the community based on a traditional cost-benefit analysis. In the case of the Jefferson Avenue Footbridge in Springfield, Missouri, the bridge posed many unanticipated challenges in the form of structural, aesthetic, and preservation requirements. The budget had to expand to meet these challenges.
Ultimately, Springfield's commitment to honor its past and renew "relationship bridges" within the community helped leverage financial support for the project. The City collaborated with public agencies (federal, state, and city) and community organizations to fund the $637,000 construction cost.
Last September, the community celebrated the centennial of the bridge, taking pride in its completion as well as the links it represents. While the bridge provides safe pedestrian transit across the 13-track rail yard, its value to the Springfield community exceeds the pure function of the structure. A tangible link to the city's roots as a railroad boomtown, the bridge offers a symbolic and highly visible link between a historic commercial district and a residential neighborhood. It also creates a focus and public venue for community events and renewed interest in Springfield's history.
Springfield grew up with the railroads. Erected in 1902, the Jefferson Avenue Footbridge gave railroad families a safe way to cross the former St. Louis-San Francisco (now BNSF) railroad tracks from the north-side Woodland Heights residential area to the retail shops, theaters, and offices on Commercial Street on the south.
But time took its toll. The bridge structure deteriorated and had been an ongoing safety and maintenance concern for the City. Though spot repairs were made over the years, the City knew the aging structure would require extensive work.
In 1993, Mary Collette, a Springfield graphic artist, photographer, and current City Councilmember who lives nearby and works in the Commercial Street District, learned about a bridge renovation in Chattanooga, Tennessee.
"What resonated for me was how the area around that bridge changed after the historic renovation," she says. Collette, then president of the Commercial Club, Springfield's oldest service organization, took the project to Bob Turner, then Springfield's Assistant Director of Public Works. The Public Works Department went forward with the grass-roots initiative.
Funding the Project
City officials knew they could not fund the bridge rehabilitation solely from its street maintenance budget, so they sought alternatives. In 1994, the City received a $130,000 grant from the Missouri Department of Transportation (MoDOT) Enhancement Funds through ISTEA, the Intermodal Surface Transportation Efficiency Act. The City earmarked $60,000, and the project was underway.
"MoDOT granted ISTEA funding for this enhancement project because of its historical significance, the intermodal pedestrian connection and the surrounding landscaping and beautification," says Becky Baltz, P.E., Assistant District Engineer, MoDOT District 8.
With funding secured, engineers with Affinis Corp. (formerly Larkin Group Consulting Engineers) and John Burk Construction, Inc., proceeded with the project. However, they discovered that the deterioration was worse than what the initial non-destructive structural inventory and condition rating indicated. For example, they did not know the extent of the structural damage and the rehabilitation that would be required until the bridge deck was cut away. Selective demolition revealed deteriorating structural steel members and crumbling concrete.
Thus, by April 1998, rehabilitation costs had increased, and the City explored additional funding opportunities. Ultimately, numerous civic groups, public agencies, and even private citizens supplemented the original ISTEA grant and City allocation:
Jim Anderson, President of the Springfield Area Chamber of Commerce, echoes her sentiments: "The project is practically a poster child for public/private partnerships. I'm a fan of leveraging resources. This project would not have been realized without public and private resources."
Impact of the Footbridge Rehabilitation
Rehabilitating the Jefferson Avenue Footbridge involved replacing pier footers, adding deck stringers to increase load capacity, adding to or replacing deteriorated and undersized structural members, water blasting to remove the old finish, painting, and improving the north and south pedestrian plaza areas.
But the rehabilitation involved much more than pure function or a cosmetic facelift.
"There's no question the project was trying at times, and it was not an easy process," acknowledges Phil Broyles, Assistant Director, Springfield Public Works Department. "But the community support has been overwhelming. In fact, we did not anticipate the level of emotion and positive feelings this project would generate."
Engineers and public works administrators traditionally are trained to analyze functionality and cost/benefit numbers. The success of the Jefferson Avenue Footbridge rehabilitation clearly demonstrates that public works projects can deliver or trigger other benefits to a community. For example:
Springfield, like many municipalities, has come a long way from the days of limited public involvement to encourage a philosophy of public/private partnerships. In particular, the footbridge illustrates that transportation enhancement projects are much more than concrete and asphalt. They address quality of life and aesthetics. Springfield has benefited by looking beyond the bottom line to establish the viability of a project and by seeking out potential funding partners beyond traditional sources.
Springfield's experience also illustrates the wisdom of John Heywood's observation in the 1400s: "Many hands make light work." Indeed, public agencies, neighborhood organizations, and private citizens shared the costs to renovate the Jefferson Avenue Footbridge. Now, everyone in Springfield can share the results.

Any city or public agency dealing with renovation of an older structure must accept that all manner of issues and obstacles are going to surface. If your city is embarking on, or thinking about undertaking, a historic renovation project, keep the following points in mind:
