State Route 439 (SR 439) is a four-lane state highway in Storey County, Nevada. Better known as USA Parkway, the route currently connects Interstate 80 (I-80) to the Tahoe Reno Industrial Center (TRIC) located east of Reno. The existing USA Parkway was initially constructed by the industrial center's developers; however, the Nevada Department of Transportation (NDOT) agreed to assume control of the road after Tesla announced plans to build its Gigafactory at TRIC in 2014.
