State Route 378 (SR 378) was a 2.7-mile (4.3 km) state highway in Nye County, Nevada, United States. It connected the community of Round Mountain to State Route 376. The highway originated as State Route 70 in 1941 and was later renumbered to State Route 92 before becoming SR 378 in 1976. The route was removed from the state highway system by 1999 to make way for an expansion of the adjacent Round Mountain Gold Mine. [2]

Route description[edit]

State Route 378 began at a junction with SR 376 in the Big Smoky Valley of northwestern Nye County. From here, the road ran in an easterly direction towards Round Mountain.[1] Nearing the town, the route curved southeast following Mariposa Drive for about 0.3 miles (0.48 km) to its terminus at the intersection of Main Street.[3][4]

History[edit]

The route existed as State Route 70 (1942–1964) and State Route 92 (1965–1976) before becoming SR 378.

An unimproved road resembling the modern highway alignment first appears on state maps in 1941, connecting the community of Round Mountain to State Route 8A (now SR 376).[5] This road was designated as State Route 70 the following year.[6] By 1946, pavement had been placed along the route.[7]

By 1965, the SR 70 designation was removed from the highway and replaced with State Route 92.[8]

Round Mountain Road as of 2014

In the 1976 renumbering of Nevada's state routes, the recently designated SR 92 was dropped in favor of State Route 378. This numbering change was first seen on state highway maps in 1978.[9] SR 378 remained unchanged on official maps until 1999, when the route number and road itself was removed from the state highway map.[10] A new road to Round Mountain reappeared on the next version of the map, albeit realigned and without a route number.[11] The original highway alignment was enveloped by the expansion of the Round Mountain Gold Mine.
