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.
Multiple solutions have been identified through the public and engineering process and are listed as follows. The city will begin design work on these solutions and hopes to begin construction of all or some of these solutions by 2026.
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.
