State Route 447 is a state highway in the U.S. state of Nevada. The highway is almost entirely within Washoe County but does for a brief time enter Pershing County, Nevada. The highway connects the town of Gerlach to the remainder of the state via Wadsworth. Though passing through extremely remote and desolate areas of Nevada, the highway has recently gained fame as the primary route to access the Black Rock Desert, the site of the annual Burning Man festival. The state maintained portion ends at Gerlach; however the highway continues as Washoe County Route 447 from Gerlach north to the California state line near Cedarville.
State Route 427 is a 4.7-mile-long (7.6 km) state highway in the U.S. state of Nevada. It connects the community of Wadsworth in eastern Washoe County to the city of Fernley in western Lyon County. SR 427 comprises the former routing of U.S. Route 40 through the towns it serves. SR 427 also provides an eastern link to Pyramid Lake via a junction with State Route 447 in Wadsworth.
