State Highway Naming

Washington Highway
Washington Highway

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.

All of the state's roads are typed and set according to WSDOT functional classification. Of course, there are always exceptions, so the Functional Class map isn't biblical truth, but if we map the roads according to WSDOT's FC map the routing choices will be a lot better!

If you want to know more about the Federal Functional Classification check the Functional Classification article.

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.
