The City is working on solutions to improve traffic around the Costco, north of the mall. The close proximity of the traffic signal at 30th Pl W and 33rd Ave W and the traffic signal at AlderwoodMall Pkwy and 33rd Ave W/Maple Rd cause operational issues during high traffic periods. Multiple solutions have been identified which could be phased in over multiple years.
Solution #1: 30th Pl W - Right turn In & Right Turn out and Roundabout at 33rd Ave W and North (Costco) Driveway. Includes removing the traffic signal at 30th Pl W and 33rd Ave W, reconfiguring the 30th Place W approach to 33rd Ave W to Right Turn In & Right Turn Out movements only, and constructing a Roundabout at the north entrance to Costco off 33rd Ave W to improve site access and support U-turns on 33rd Ave W.
Solution #2: Add an additional westbound lane on the east leg of 33rd Ave W & Alderwood Mall Pkwy.
Solution #3: Add a traffic signal at 182nd St SW & Alderwood Mall Pkwy.
