Primary State Highway 19
PSH 19 was never officially designated as such by the state
legislature. It was the tentative PSH number in the 1960s for a proposed outer
belt around Seattle whose proposed SR number was 605. From time to time, the
issue of building an outer belt around Seattle is discussed, but the state has
no firm plans to build the route at this time.
