Washington Roads - WA 509

WA 509



SB through the inactive 176th St. interchange. These ramps were only used for construction access to Sea-Tac for construction of the 16R-34L runway (opened in 2008) and were never open to the public, but the signage is compliant. I guess there wasn't enough neighborhood support for trying to open it up to the west. The last photo is the NB entrance ramp.


WA 509 leaves its freeway and I'm about to leave 509 for 188th St. Can the shield be smaller? The digits in the shield are not up to minimum guide sign standards.

Onto 188th Street
