OMNNI Associates was recognized by the Wisconsin Department of Transportation (WisDOT) for their role in the design of the CTH KW Bridge over Pratt Creek in Dodge County. The CTH KW bridge project took the first place award in the WisDOT Excellence in Highway Design competition for the Best Local Program Design. Judy Wilson, P.E., Project Manager and Kristofer Olson, P.E., Project Engineer received the award for OMNNI Associates (see photo).
With fewer federal funds available to assist local governments, Dodge County looked for new and innovative ways to replace their deteriorating bridges. They chose to investigate a new technology known as Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS) and contracted with OMNNI Associates for the bridge design services to replace the CTH KW bridge over Pratt Creek using this new technology. Only one other bridge in Wisconsin had been constructed using this technology.
GRS is an engineered fill of closely spaced alternating layers of compacted fill and geosynthetic reinforcement. This layering eliminates the need for traditional concrete abutments. IBS is a method of bridge support that blends the roadway into the superstructure using GRS technology. The integrated system creates a transition area that allows for uniform settlement between the bridge substructure and the roadway approach, resulting in a smoother bridge approach.
The main appeal of this new GRS-IBS technology is that bridge replacement projects can be completed in as little as several weeks versus several months. Another advantage of using this technology in the future is the ability for the local government’s field staff to build the bridge themselves. Both advantages save the taxpayers money, which is the No. 1 goal in using this technology.
The award ceremony was held during the 2017 WisDOT – ACEC Transportation Improvement Conference on March 1st at the Wilderness Resort in Wisconsin Dells.
