Nevada State Highways
The original Nevada State Route system was renumbered in 1976 to its current system. This system clusters primary, secondary (urban), and secondary (rural) routes by county. The following chart shows the numbers assigned to each county, including any routes added and/or removed from the state highway system since 1976:
|Clark (Las Vegas)||142-171||562-612||738-745|
|Douglas||28, 88, 206-208||756-760|

Nevada has used the white, California-style milepost for quite a while. These markers indicate the county name, the route number, and the type of route. Interestingly, the markers are used on interstate highways in Nevada in addition to the typical Interstate green-and-white milepost markers. The numbers for the white markers are restarted at each county line, so that are found at different intervals than the green and white markers. Although California refers to these as "postmile markers," Nevada refers to their version as "mileposts."
Each Nevada milepost has an abbreviation indicating the class of the route: "IR" for Interstate, "US" for U.S. routes, and "SR" for all state routes. Sometimes these markers are the only indication that a road is maintained by the Nevada Department of Transportation (NDOT). These markers are the only indications that some of the unsigned highways are maintained by NDOT.
Nevada uses two-letter abbreviations while California uses three letters. This is likely due to the fact that Nevada has only 16 counties while California has 58 counties. California's situation is further complicated by the fact that eight of them begin with "M" and a whopping 18 of them begin with "S." Of those "S"s, 10 of them begin with either "San" or "Santa". So, California has no choice but to use three letters to make clear differentiations. Even with three letters, sometimes the combinations they choose are a bit arcane: SBT for San Benito, SBD for San Bernardino, and SBA for Santa Barbara; SCL for Santa Clara, and SCR for Santa Cruz. California uses only two letters for LA (Los Angeles), SD (San Diego), SJ (San Joaquin), and SF (San Francisco). The following is a complete list of all two-digit county codes for Nevada Mileposts. These abbreviations are also used in the State Highway Lists.
