PSH 5
Primary State Highway 5 was a major state highway in the U.S. state of Washington.
PSH 5 started on S Dearborn St at the intersection of Seattle Blvd S. The route then connected to Rainier Ave S (modern day SR-900), where it continued. The route then connected to the West Valley Highway (modern day SR-181) where its terminus was at the end of the highway. The highway had many branches, which have all been replaced by modern day highways such as SR-515, SR 181, and SR-900.
