Local naming variations
- Nevada State uses NV-##, and NV-##X for all state routes and their spurs, loops, etc. (e.g. NV-27, NV-17M). When working on an area, if you encounter a road with the old SR-## naming, please take the time to change that name to reflect the NV-## name. This includes alternate names, if you notice them.
Functional Classifications
Nevada is following the Functional Classification (FC) system for the USA.
Lock Levels
In Nevada we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
| Segment Type | Urban Areas | Rural Areas | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Freeway | 5 | 4 | |||||||||

NOTE: Streets directly involved in the Las Vegas Strip area should be minimum locked at one level higher than the above minimums, to protect that vital traffic corridor.
Please note that the above lock levels are subject to change, pending final approval of those levels.
