WI DOT receives FHA grants for bridge work in Wood County

Jun 20, 2011Grant Announcements

The Wisconsin Department of Transportation has received several grants from the Department of Transportation's Federal Highway Administration as part of its Innovative Bridge Research and Deployment (IBRD) Program. This program was established "to promote, demonstrate, evaluate and document the application of innovative designs, materials, and construction methods in constructing, repairing, and rehabilitating bridges and other highway structures."

The first grant, in the amount of $30,000.00 is for work on the bridge over Shelby Creek, a slab span structure consisting of a single span of 22-feet in length and a 34 feet wide. The proposal by WisDOT to use GRS bridge abutments in the replacement bridge is a cost effective solution for this type of project. Officials will gain significant experience from this project and determine whether it is a good alternative for other projects throughout the State. The use of GRS is one of the market-ready innovative technologies being promoted by FHWA under the EDC initiative.

The second grant award, totaling $327,300.00 is for work on a bridge over Mosquito Creek, a slab span structure with two spans of 21-feet each and a width of 34 feet with a 40-ton load posting. The Wisconsin Department of Transportation (WisDOT), through its in-house research, has developed precast abutment systems. Officials of WisDOT are proposing an innovative accelerated construction technique of combining approach slab and bridge deck with a special ductile concrete joint. The accelerated construction of the project will improve work zone safety and the innovative superstructure construction technique will eliminate the dangerous construction activity of form removal. The project supports the use of Prefabricated Bridge Elements and System, a technology being promoted by FHWA under the EDC initiative.
