Madison, WI – A bridge built with prestressed concrete elements manufactured by County Materials Corporation earned special recognition from the Wisconsin Department of Transportation. The agency presented the Special Recognition Award to Lunda Construction Company on January 29 as part of the Excellence in Construction Awards held during the Wisconsin Transportation Builders Associations’ annual Contractor-Engineer Conference in Madison.

The bridge spans Siggelkow Road in Dane County, and is part of the I-39/90 Expansion Project currently underway to address safety and congestion concerns between Madison and the Wisconsin/Illinois border. Lunda Construction worked closely with County Materials to complete the project, which utilizes an accelerated bridge construction (ABC) process. The precast bridge columns, girders and pier caps used allow for faster bridge construction, which minimizes road closures and saves countless hours of commuter time. ABC also reduces overall project costs.

County Materials supplied twenty 45W pre-stressed girders (each 110’ to 116’ long); five 16’5” tall, 3’6”x4’ pier columns; and two 39’ long pier caps for the Siggelkow Road bridge project. The pier caps approached 100,000 pounds each, and were hauled to the site with a specialized transporter.

The project required a great deal of cooperation between County Materials, Lunda Construction, and WI DOT. Lunda Construction did the formwork and fabricated the templates, and County Materials tied the rebar cages and executed the pour. “It’s a special job that everyone worked well together on,” says Laremy Sacia, Project Manager at Lunda Construction.

The Siggelkow Road bridge is the first on the I-39 corridor to utilize ABC techniques. WisDOT expects ABC construction to benefit similar projects in the future. “This project allowed us to gain an understanding of the constructability for these types of prefabrication and assembly techniques and demonstrates the department’s use of innovative construction methods used to accelerate bridge construction – that is, ABC concepts,” said Daniel Tyler with WisDOT’s Bureau of Project Development. “These techniques and practices will become increasingly valuable tools to help us manage schedule constraints, motorist delays, and fiscal demands.”
