State highway naming

Nebraska Highway

State highways are to be named N-### [1]
(TTS pronunciation "Nebraska ###")

Nebraska Link

State Links are to be named L-##X [2]
(TTS pronunciation "Nebraska Link ##X")

Nebraska Spur

State Spurs are to be named S-##X [3]
(TTS pronunciation "Nebraska Spur ##X")

Nebraska Recreation Road

State Recreation Roads are to be named R-##X [4]
(TTS pronunciation "Nebraska Recreation Road ##X")

Additional:
  1. State highways never share the same number as any U.S. or Interstate highway that runs through the state.
  2. A Link is a highway that connects two major highways.
  3. A Spur is a highway that connects a major highway to a city or town where no other highway exists.
  4. Recreation Roads are the roads contained within a State Park and are almost never signed but do appear in NDOR and FC maps.

County road naming

County roads with the name designation of "County Road ##" or "Co Rd ##" are to be named in Waze as CR-##. This shortened version takes up less space on the map screen and is announced correctly as "County Road ##" while navigating with the Waze app.

Roads named N, S, E or W

If you encounter any roads that are named N, S, E, or W, you must add a period (.) to the end of the letter. For example, West N Street is abbreviated as W N. St. County Road W is abbreviated as CR-W., and so on. This ensures the TTS system reads the road name as "County Road W" and not "County Road West." This does not apply to Nebraska state highways abbreviated as N-##X or Spurs abbreviated as S-##X. Waze recognizes these as state highways and spurs, respectively, and pronounces them correctly.

Locking standard

In Nebraska, we observe a minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank listed in the chart below. Roads may be locked higher for protection and special situations (construction, confusing design, frequent mistakes, image inaccuracies, etc.), but should not be locked lower.

Nebraska Minimum Locking Ranks
Segment Type Rank
 Freeway  4
 Ramp  4
 Major Highway  4
 Minor Highway  3
 Primary Street  2
 |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-|  2
All Others 1

Although common practice is to limit editing freeways to rank 5 or higher, we have determined that the experience required to reach editing rank 4 is sufficient to gain the privilege of editing freeway segments.

Nebraska Functional Classification

For the most part, Nebraska's Functional Classification is pretty straightforward. Nebraska divides its FC in to two classes, Urban and Rural. There are several several road types listed as Urban Principal Arterial. Because Waze only identifies a single Principal Arterial category, the Connecting Link and Non-Connecting Link Principal Arterial categories are considered the same. Interstates and Other Freeways & Expressways are always drawn as a  Freeway  despite being listed under Urban Principal Arterial.

Below is a modified table that matches the Nebraska Functional Classification with the Waze Road Types.

^a There are no current bannered Interstates in Nebraska.

U-turns

U-turns are permitted in Nebraska except where prohibited by signage or restricted by local municipal law. [1][2]

For Waze routing, u-turns should only be enabled where they provide the potential for improved routing, which includes recovering from missed turns. A common example is a median-divided primary street that has homes/businesses with their driveways/entrances directly on it, where reaching them would otherwise require lengthy, multi-turn deviations through side roads in order to end up on the correct side of the median.

The u-turn must also meet one of the following criteria:

  1. The u-turn is explicitly allowed by signage OR
  2. The u-turn is otherwise legal and safe, and there is at least 10.1 m (33 feet) from the left edge of the departure lane to the "destination" curb. This can include any median that may exist to the left of the departure lane. (This is to ensure the turn can be completed in one continuous movement, which is a legal requirement in many places)

Note that when editing, a functional u-turn can arise from more than just the u-turn flag on a road segment, such as with these common scenarios:

  1. Divided roads with box and partial-box intersections where the median segment is 15 m (49 feet) or longer.
  2. Divided roads with explicitly-mapped inside turn lanes unless the turn arrow in the u-turn direction is disabled.
