A half mile stretch of Locust Street, one of the main highways from I-80 into the city of Grand Island, was beginning to settle. Sections of the road had dropped two to three inches, making it increasingly unsafe for motor vehicles, particularly motorcycle travel. The City of Grand Island was also in preparation for the Nebraska State Fair which would draw an estimated 300,000 people to the area, placing an extra emphasis on the roadway being ready.
Several options were considered, including complete tear-out and replacement as well as grinding, patching and sealing. Since the majority of concrete was in good shape, rather than replace or patch, the city decided to put out a request for proposals using polyurethane foam to address the settlement.
Thrasher was chosen to install PolyLevel 400h, a polyurethane foam, to address the settlement issues. The crew of three Thrasher employees spent three and a half weeks installing PolyLevel to void fill, lift and level the road. During the process, one northbound lane and two southbound lanes remained open at all times, minimizing the disruption to traffic.
A total of 45,000 lbs. of material was installed, bringing the uneven surface back to level. A coordinated effort between The City of Grand Island and Thrasher made the project a success, being completed in less time than the 5 weeks permitted and before the Nebraska State Fair.
