With a critical schedule and the need for a design that could be constructed easily and in keeping with the context of the site and the architecture of the nearby Kauffman Center for the Performing Arts and Kansas City Convention Center, MoDOT selected a design team led by GBA to deliver a solution that is more than meeting expectations.
Completed on schedule and on budget, MoDOT’s new replacement bridge on Broadway over I-670 is providing an important link in this key pedestrian corridor.
As part of a long-term maintenance plan, MoDOT has repaired and replaced bridges spanning I-670 on the south side of Kansas City’s downtown loop. With the Broadway Bridge scheduled for extensive rehabilitation, MoDOT took a closer look and determined that replacement was the best option. A new structure would provide wider, safer sidewalks in this critical pedestrian corridor, which connects the Central Business District with the Crossroads Arts District. But the bridge would have to be designed and constructed quickly, in time for the opening of the Performing Arts Center.
MoDOT selected GBA teamed with el dorado inc., Kleinfelder, and Hg Consult, Inc. to design the pedestrian-friendly replacement bridge. “In forming our team, we were very aware of the critical nature of the schedule and the need to create a design in keeping with the context of the site,” said GBA Project Manager Tawn Nugent, P.E. “Our approach was to bring forth solutions that would save money and that would be critical to the overall success of the project.” Nugent credits collaboration among the various stakeholders involved as the key to finding workable solutions. The design team met regularly with representatives of MoDOT, the City of Kansas City, and the Downtown Council, and worked closely with KCPL, the Crossroads Arts District, the West Side Community Action Network, and others.
The schedule presented one of the greatest challenges for designers charged with creating high-quality design plans for the $4.9 million project. “Typically a project of this magnitude would be a year in planning and design,” said Nugent. In this case, innovative bridge design concepts were analyzed and developed and final plans delivered on February 14, 2011, just three months after notice-to-proceed. Clarkson Construction, Inc., the contractor, started work in early May and delivered the completed project just five months later.
The bridge itself is 350 feet long and 77 feet wide. It accommodates five lanes of traffic and includes 10-foot-wide sidewalks on either side. Cost-effective aesthetic features include energy-efficient accent lighting, decorative mesh, and noise abatement panels incorporated into the pedestrian barriers. “When the bridge was originally designed, the principal audience was vehicular,” said David Dowell, a principal with el dorado inc., which provided architectural and artistic enhancement. “The new bridge also accommodates vehicles, but the experience of pedestrians has been elevated as a priority.”
With the work now completed, motorists and pedestrians alike are enjoying the aesthetics and access provided by this significant new structure.
