The project, which received an additional $975,000 in funding from the Road Repair and Accountability Act of 2017, involved the stretch of I-80 to be resurfaced with a Rubberized Hot-Mix Asphalt overlay. The purpose of the project is to enhance durability and provide smoother traveling on the highway.

Additional enhancements include shoulder rumble strips and 6-inch thermoplastic striping for better awareness and visibility in all weather conditions, officials said, and upgraded electrical facilities at seven locations along the I-80.
