State Route 427 (SR 427) is a 4.7-mile-long (7.6 km)state highway in theU.S. state ofNevada. It connects the community ofWadsworth in easternWashoe County to the city ofFernley in westernLyon County. SR 427 comprises the former routing of U.S. Route 40 (US 40) through the towns it serves. SR 427 also provides an eastern link toPyramid Lake via a junction withState Route 447 in Wadsworth.

SR 427 begins at a cattleguard on Cantlon Drive just south of the Wadsworth/Pyramid Lake interchange (Exit 43) onInterstate 80 (I-80) in Washoe County. The highway proceeds northeast from there to meet State Route 447 in the middle of Wadsworth. The route curves southeast through the town and immediately enters Lyon County. Passing south under I-80 once again, as well as theUnion Pacific railroad tracks, SR 427 curves east to follow Main Street/Truckee Lane into Fernley. The highway ends at the intersection withUS 50 Alt. andUS 95 Alt. in Downtown Fernley.[1]
Originally, US 40 followed the routing of SR 427 through Wadsworth and Fernley. Completion of I-80 around both cities (and many other northern Nevada cities) made the U.S. highway designation irrelevant and US 40 was later removed from the highway system.
