County Road Naming
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.
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
