AAA FOUNDATION FOR TRAFFIC SAFETY

Sparks, NV: Planning a New 4-Lane Highway

Currently, the USA Parkway is a privately built, six-mile-long road connecting from Interstate 80 into the Tahoe Reno Industrial Center east of Sparks. A proposed NDOT project will extend the Parkway by more than 12 miles to reach U.S. 50 near Silver Springs, creating an approximately 18-mile-long, four-lane state roadway between Interstate 80 and U.S. 50.
