If you happened to be in the Village of Ellsworth, WI on July 26th, 2019, you would have witnessed an awe-inspiring joint effort between County Materials’ heavy-haul drivers, the company’s dispatch team and local law enforcement. In a single day, County Materials transported five 136 foot-long and 140,000lb concrete prestress I-beam bridge girders from Roberts, WI 50 miles south to Plum City, WI. The extreme length of the girders required the drivers to carefully maneuver through a traffic light island going in the wrong direction. With the help of local law enforcement and the erector’s ability to unload and install all the girders in one day, traffic was only minimally impacted in the Village of Ellsworth.
Not only was transportation of the girders to the jobsite an extreme challenge navigated by County Materials’ heavy-haul drivers, staging at the job site also required unique problem solving. This project involved the complete replacement of a bridge along Wisconsin Highway 10. The roadway weaves through a hilly landscape leaving a narrow area for construction. Unloading took place on a small temporary bridge that was constructed to keep traffic flowing throughout the construction process.
The WISDOT 72W girders for this job stand six feet tall and were specifically engineered and manufactured in County Materials’ Roberts, WI indoor, climate-controlled production facility to meet the exacting standards of the Wisconsin Department of Transportation. During the manufacturing process, County Materials embeds rebar loops into the girders, so they are ready to lift with no additional work onsite and are instantly ready for installation. After the girders were delivered, the bridge reopened before the end of the summer.
