State Highway Naming
State highways are to be named SR-###
Washington State highways should be current to our wiki standard,
if you see one that doesn't seem right contact one of the SM's.
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.
Locking Standard
Washington observes the following locking standards on the following types of road segments. All roads must be locked at least to the minimum level stated. Roads may be locked higher for protection and special situations (construction, confusing design, frequent mistakes, image inaccuracies, etc.), If needing a segment unlocked or locked to a </> level please use the Unlock and Update Request forum.
| Segment Type | Rank |
|---|---|
| Freeway | 4 |
| Ramp | 4 |
| • • • • Ferry • • • • | 4 |
| Major Highway | 3 |
| Minor Highway | 2 |
| Primary Street | 2 |

Road Elevations
These are the general guidelines for elevation in Washington:
- Drivable and non-drivable segments are handled the same way with elevation.
- Set elevation to ground in most cases.
- Segment(s) passing over other segment(s), rivers, major waterways, and all bridges shall have higher elevation, relative to ground.
- Only elevate/lower the actual bridge/tunnel section of the road.
- Elevation of overlapping segments should be set relative to each other, with the lowest segment as Ground (unless a tunnel).
- Tunneled segments shall have lower elevation, relative to ground.
- Only segments that "cannot see the sky" should have negative elevation (i.e. tunnels).
- Only set elevation as low/high as necessary.
- If you use the Bridge tool to join segments, be aware that it raises the elevation of the joined segment. Lower the joined segment as appropriate.
- "True Elevation" guidelines apply to elevation in Washington.
- Bridges should be cut at the start/end of the bridge.
- Tunnels should be cut at least 15m/50ft before and after the tunnel, to allow time for the GPS to regain signal.
- Do not cut segments for elevation purposes if the bridge/tunnel starts/stops within 60m/200ft of an existing junction.
Speed Limits
Washington follows the US wiki Speed_limits/USA for adding speed limits to the map.
Local guidance will be listed on the Washington speed limit page Washington/Speed limits
