List of former state routes in Nevada
The following is a list of state routes in Nevada longer than in length that have been removed from the Nevada state highway system since 1976. Several of these highways were reorganized into the state system of frontage roads. State Route 144. State Route 144 (SR 144) in Mesquite was also designated as Interstate 15 Business. It was removed as of December 31, 2005. It covered Mesquite Boulevard and Sandhill Boulevard in Mesquite. The State Route designation was applied to the portion of Mesquite Boulevard from its southern crossing of Interstate 15 to  Sandhill Boulevard, then along Sandhill Boulevard to its northern crossing of Interstate 15. The route was long. Route 144, from SR 170 to Hillside Drive, was once US 91, which used to stretch from Sweetgrass, Montana to Long Beach, California. State Route 166. State Route 166 was a Nevada state highway that was signed along Lakeshore Road in Clark County. The road still runs along the west shore of Lake Mead, but is no longer a state highway. SR 166 started at an intersection with US 93 near Boulder City inside the Lake Mead National Recreation Area. The highway went  north along Lake Mead's shore. It quickly encountered a toll booth where motorists paid to enter the recreation area. Several roads branched off SR 166 and lead to marinas. Near the end of its route, the highway turned west before meeting its northern terminus, at an intersection with SR 564/SR 147. Signage for the route was removed by 2000, and according to a park ranger, the route is a park service road, and the signs were only put up to "make it easier for tourists." State Route 167. State Route 167 was a Nevada state highway that was  signed along Northshore Road in Clark County. The road still runs along the west shore of Lake Mead, but it is no longer a state highway. SR 167 started at SR 147 inside the Lake Mead National Recreation Area. The road went east along Lake Mead's shore. It eventually turned north near Echo Bay. A road branched SR 167 and led to Echo Bay Airport, and another road led to Overton Beach on Lake Mead. The road turned west and quickly reached its northeastern terminus at SR 169. State Route 291. State Route 291 (SR 291) was a two -lane state highway in Humboldt County. It served a sparsely populated section of the state, connecting northwestern Nevada to southern Oregon. Most of the highway was originally part of SR 8A, and was later improved through an effort to provide an all-weather highway linking northern Nevada to the Pacific Northwest. When Nevada officials began the process of renumbering the state's highways in 1976, SR 140 was planned to be redesignated as State Route 291. The proposed route number was first seen on the 1978 version of the state's highway map. Once the renumbering process was finished in  the early 1980s, however, the highway retained the SR 140 designation it has today. The route has remained relatively unchanged since. State Route 378. State Route 378 (SR 378) was a state highway in Nye County. It connected the community of Round Mountain to SR 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. 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. Nearing the town, the route curved southeast following Mariposa Drive for about to its terminus at the intersection of Main Street. An unimproved road resembling the modern highway alignment first appears on state maps in 1941, connecting the community of Round Mountain to SR 8A (now SR 376). This road was designated as SR 70 the following year. By 1946, pavement had been placed along the route. By 1965, the SR 70 designation was removed from  the highway and replaced with SR 92, potentially to align the 70 designation to a road that met with California's State Route 70. 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. SR 378 remained unchanged on official maps until 1999, when the route number and road itself was removed from the state highway map. A new road to Round Mountain reappeared on the next version of the map, albeit realigned and without a  route number. The original highway alignment was enveloped by the expansion of the Round Mountain Gold Mine. State Route 428. State Route 428 (SR 428) is a former highway in Washoe County. It followed "Eastlake Boulevard" through New Washoe City and along the east side of Washoe Lake, providing access to Washoe Lake State Park. The road was formerly known as State Route 3B. State Route 428 began at US 395, near the present-day Eastlake Boulevard interchange just north of Carson City. From there, the highway curved north to follow the eastern shores of Washoe Lake. Near the northeast  corner of the lake, the road diverged north to head towards New Washoe City. Outside of the town, SR 428 terminated at another junction on US 395 between Washoe City and Pleasant Valley. Eastlake Boulevard first appears on state highway maps in 1942 as State Route 3B, an unimproved road branching from State Route 3 (now US 395 Alt) at both ends. The highway had been completely paved by 1969. The route underwent no significant other changes until it was renumbered as State Route 428 in the 1978 statewide highway renumbering. State Route 428 disappeared from state highway maps by  1983. However, the southern of the highway, near the Interstate 580/US 395 interchange, are still maintained by NDOT as a frontage road (FR WA45). State Route 429. State Route 429 (SR 429) was a rural state highway located in southern Washoe County. It followed Bowers Mansion Road, a former alignment of US 395. The SR 429 designation was retired in 2012, and the route has since become part of US 395 Alt. SR 429 began at Hobart Road, near the Carson City – Washoe County line immediately adjacent to present-day Interstate 580 (I-580) and US 395. From this point , the SR 429 paralleled US 395 northward for about and then shifted westward to follow the foothills of the mountains to the west. The highway continued northward past Bowers Mansion State Park before turning east to terminate at US 395 just south of Washoe City. State Route 485. State Route 485 (SR 485) was a state highway in White Pine County. It provided access to the town of Ruth. The roadway was turned over to local control in the 1980s. SR 485 started at US 50, about west of Ely. SR 485 ran west to the mining town of Ruth . The road's pavement ends slightly west of Ruth, although a dirt road continues back near the former site of Riepetown. The road to Ruth was established as State Route 44 by 1935. At that time, the route was shown on official state maps as being a paved road connecting the former town of Kimberly to US 50 via Ruth. By 1941, SR 44 appears to have been altered and then comprised two roadways, a road to Ruth and a spur to Kimberly;. a routing which was defined by state highway law. Although maps are unclear, it appears the road  to Ruth was eliminated prior to 1964, and the spur to Kimberly was retained as SR 44. The town of Ruth may have been relocated along the highway as well, in concordance with open pit mining operations in the area. SR 44 remained unchanged for many years, until the 1976 renumbering of Nevada's state highways. In that process, SR 44 was to be replaced by SR 485. However, the new designation was not retained through the state's renumbering process; SR 485 last appeared on the 1980–1981 state highway map while the numbering transition was still underway. State Route  486. State Route 486 (SR 486) was a state highway in White Pine County. The roadway was turned over to local control in the 1990s. Immediately before the route number was retired, the SR 486 designation encompassed Duck Creek Road, which started at the south end of pavement in the middle of Duck Creek Valley. It went north down the valley, then turned west and exited at Gallagher Gap, following the course of Duck Creek. Once through the gap, it continued west until it intersected US 93, where it ended. The road extending east from US 93 to Duck Creek  Valley (Duck Creek Road), south over Success Summit to Cave Lake State Park (Success Summit Road), and back west to US 6/US 50/US 93 (Steptoe Creek Road) appeared on state maps before the 1976 renumbering of Nevada's state routes, but had no state designation. The designation of SR 486 was first seen on state highway maps in 1978 and included the entire loop (known as Success Loop), but was scaled back to the paved northern portion by 1982. SR 486 remained unchanged on official maps until 1995, when the route number was removed from the state highway  map. The entire loop is now part of White Pine County Route 29, though some agencies, including the Nevada Division of State Parks and Humboldt-Toiyabe National Forest, still refer to part or all of the road as SR 486. State Route 489. State Route 489 (SR 489) was a state highway that connected the near ghost town of Cherry Creek to US 93 in White Pine County. The roadway was turned over to local control in the 1990s.The SR 489 designation started at US 93. It went west across Steptoe Valley and ended at the end of pavement  in Cherry Creek, which is now almost deserted but was once a thriving town because of silver and gold located in the area. Cherry Creek Road continues west, however the section west of Cherry Creek has never had a state route number. Before the 1976 renumbering of Nevada's state routes, the road from US 93 to Cherry Creek was designated SR 35. The change to SR 489 was first seen on state highway maps in 1978. SR 489 remained unchanged on official maps until 1993, when the route number was removed from the state highway map. Both the paved  and unpaved sections of Cherry Creek Road are now part of White Pine County Route 21. State Route 500. State Route 500 (SR 500) was a state highway located in Boulder City. It ran for about along the original route of US 93 and historical US 466 on the Nevada Highway (former State Route 26) through the middle of town. It came into being when the US 93 designation was moved to a new "truck bypass" alignment along the upper reaches of Hemenway Wash in 1982. After being turned over to local control by NDOT, the street was renamed as  Nevada Way by the city. State Route 501. State Route 501 was a state highway in Boulder City. It ran from US 93 to State Route 500 near City Hall in Boulder City via Adams Boulevard and Utah Street. The route was turned over to local control in the 2000s. State Route 512. State Route 512 (SR 512) was a state highway in Carson City, Nevada. It connected Kings Canyon west of Carson City to the state capitol using various city streets. The route dates to the mid-19th century, as part of a wagon trail linking Lake Tahoe and Carson  City that was later incorporated into the Lincoln Highway. SR 512 was turned over to local control in 2010. State Route 513. State Route 513 (SR 513) was a short state highway in Carson City, Nevada. The route was originally part of State Route 65, a longer highway that served the eastern outskirts of the city. SR 513 was turned over to Carson City in phases, and completely removed from the state highway system in 2011. State Route 513 began at the intersection of Fifth Street and South Carson Street (US 395 Business/SR 529) in downtown Carson City. At  the northeast corner of this intersection is south end of the Nevada capitol complex. SR 513 headed east along East Fifth Street, passing by the Nevada Legislature building and other state facilities. Crossing Roop Street, the route entered a more residential area of the central city. After about a mile (1.6 km), SR 513 became a two-lane road through more open areas. Fifth Street then rises over the Carson City Freeway (US 50 and 395) and touches down next to Nevada State Prison. In 2011, the state highway ended at a roundabout intersection with Fairview Drive just past the  prison facility. State Route 516. State Route 516 (SR 516) was a state highway following Ormsby Boulevard and Winnie Lane in Carson City, Nevada. The route was turned over to local control in 2010. The highway began at the intersection of Ormsby Boulevard and West King Street (SR 512) in a residential area of western Carson City. From there, the route went north on Ormsby Boulevard through residential areas and fields before curving west. After approximately one mile (1.6 km), the route intersected Winnie Lane. SR 516 followed Winnie Lane north and east from this intersection, passing about through more  neighborhoods before ending at North Carson Street (US 395 Business/SR 529). State Route 516 was designated a state highway in 1983. This change was seen on the state highway map in 1982. A transfer of ownership of several state highways to Carson City's control was proposed by 2007. The shift in ownership, which included SR 516, was proposed in order to reduce the amount of money the city was supposed to pay to the Nevada Department of Transportation for the construction of the Carson City Freeway (future Interstate 580). State Route 516 was removed from the state highway  system by January 2010. State Route 518.
