This dates to the original US highway system, in which US-410 was a signed auxiliary stretching from Aberdeen to well beyond the Idaho line. The opening of an all-weather highway through White Pass left the seasonal Chinook Pass route obsolete. At the same time, decommissioning of US-10 west of the Twin Cities left 410 without a parent, and the Aberdeen-Missola route became an extension of US-12. The remaining segment of 410 between Elma and Naches was split up into SR-8 and SR-410 in 1969. It was only in the 1970's with the construction of the Valley Freeway and SR-512 that River Road was resigned as 167, with the intent that its ultimate freeway replacement would form part of a continuous bypass route for I-5.

The Tacoma section of the WA 509 freeway will for sure be extended past Port Of Tacoma Rd in the SE direction - as a WA 167 extension. The WA 167 freeway section currently ends in Puyallup, and the need to extend is based on the heavy truck traffic that inundates Valley Ave between I-5 and Puyallup. 5 new interchanges will be constructed including a 4 level stack with I-5. I would not be at all surprised though if the new freeway gets the WA 410 designation instead due to the direction of travel. Another proposed freeway would follow WA 509 into Federal Way and connect to the WA 18/I-5 cloverleaf (which will become a semidirectional Par clo in the future). Also of note is that the northern section of WA 509 freeway is slated for southward extension from S 188th St in a SE direction to I-5 near S 210 St. Four new interchanges are planned - including a South Airport Access Road. More later .....
