The following is a list of all past and present state maintained highways and other regionally significant highways located in the U.S. state of Nevada. All active numbered highways (including Interstates, U.S. Routes and State Routes) in this list are maintained by the Nevada Department of Transportation, except for the portions of Interstate 215 and where otherwise stated.

[edit] United States Routes
[edit] Current
[edit] Former
These U.S. Routes were mostly replaced in Nevada by Interstate routes. All were officially removed from the state highway system by 1978.

[edit] Current numbering system (1978-present)
[edit] Primary routes (SR 28 - SR 490)
Primary state routes are assigned numbers based upon the county in which the majority of the route resides (or, in some instances, the county of the major town on the route). State routes in a county are grouped together with similar numbers, which are assigned in order based upon alphabetical order of county names. Three exceptions to this numbering scheme exist (SR 28, SR 88, and SR 140); all three of these routes have highway numbers that continue into the adjoining state.
- Note: Shaded routes have been decomissioned. An asterisk indicates a route number that may not have been assigned.
[edit] Urban routes (SR 500 - SR 686)
Urban state routes, numbered in the 500's and 600's, typically lie on arterial roadways in larger metropolitan areas. Urban state route numbers are grouped together sequentially, assigned by alphabetical order of the name of the city in which they primarily reside.
Nevada DOT has been deleting urban routes from the state highway system in recent years. This is especially apparent in the Las Vegas and Reno metropolitan areas.
- Note: Shaded routes have been decomissioned. An asterisk indicates a route number that may not have been assigned.
[edit] Secondary routes (SR 701 - SR 900)
Minor state routes, numbered in the 700's and 800's, chiefly exist to connect smaller rural communities to other state highways. In some small urban areas, these routes can also serve as minor collector or arterial roadways.
Like primary state routes, minor state routes are grouped sequentially in alphabetical order by county name.
- Note: Shaded routes have been decomissioned. An asterisk indicates a route number that may not have been assigned.
[edit] Previous numbering system (1917-1978)
These State Routes were developed beginning in 1917 upon the creation of the Nevada Department of Highways. Routes were not assigned according to any particular numbering system, and sequential numbers were largely scattered throughout the state. Additionally, several suffixed highways were also designated, branching from the original parent route.
During the statewide route renumbering that began in 1978, the majority of Nevada's two-digit state routes were eliminated. Most of the old two-digit routes were reassigned to one or more of the new three-digit highway numbers (State Routes 28 and 88 were the only routes to permanently keep their pre-1978 numbers). Other routes were immediately eliminated from the state highway system, while a select few retained their pre-1978 numbers on official state maps into the 1980s only to be later reassigned or decommissioned.
