The Washington State Department of Transportation (WSDOT) will be ramping up work this week on the SR 167 Corridor Improvements Project. Upgrading the tolling system and adding lanes along portions of State Route 167 (SR 167) is the bulk of this project, expected to wrap up in early 2026. When completed, drivers will have a continuous tolling system that stretches from State Route 512 (SR 512) in Puyallup to the Interstate 5 (I-5)/Interstate 405 (I-405) interchange in Lynnwood. The toll lanes give drivers an option to get through traffic quicker, at a price.
