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.
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.
