Illinois Tollway Engineers See Production of Girders for Mile Long Bridge

With the Mile Long Bridge construction underway in Chicago, IL, representatives, engineers, and communications personnel from the Illinois Tollway toured County Materials’ state-of-the-art prestress manufacturing facility in Janesville, WI. County Materials began production in summer 2019 and is slated to produce a total of 273 girders for the project.

On January 10th, County Materials hosted thirteen engineers from the Illinois Tollway. The engineers were able to watch the County Materials team prep for the building, casting, and stripping of the first of twenty-two 185.5-foot-long, 245,000 lb. girders—the largest girders produced in the Midwest region to date. On January 13th, County Materials successfully completed the first of these girders. Several of the engineers noted the value in seeing the girder production first-hand. 

On January 24th, County Materials hosted a second tour made up of Illinois Tollway representatives and communications personnel. The Illinois Tollway team toured the facilities because the Mile Long Bridge is a critical piece of infrastructure to the Central Tri-State Tollway (I-294) corridor. It carries drivers over two major railroads, three water resources and local roads, and over a major distribution center for UPS and Burlington Northern Santa Fe (BNSF) Railway. Working directly with County Materials has helped the Illinois Tollway construction team ensure the successful delivery of the first stages of the bridge.

The Mile Long Bridge Project is scheduled for construction from 2019 through 2023. It includes the construction of two new, wider bridge structures and storm water and drainage improvements.

County Materials is an active participant in promoting industry education. Our company manufactures prestressed concrete girders which contribute to long-lasting infrastructure and offer lower life cycle costs compared to other methods of construction.
