SR 167 Corridor Improvements Project

Project overview

The SR 167 Corridor Improvements Project is comprised of the SR 167 Toll Equipment Upgrade Project and the SR 167, SR 516 to South 277th Street Southbound Auxiliary Lane Project. As part of the SR 167 Toll Equipment Upgrade Project, we plan to update the SR 167 toll system to create consistency along the I-405/SR 167 corridor. This project would upgrade the SR 167 toll equipment to be the same as the I-405 toll equipment, resulting in a continuous 50-mile I-405/SR 167 express toll lane system and a consistent customer experience in the express toll lanes. We also plan to construct an auxiliary lane on southbound SR 167 between SR 516 and South 277th Street in Kent.

Once the project is complete, travelers will experience new, modern SR 167 express toll lanes that tie into the Renton to Bellevue I-405 express toll lane system, currently under construction, and the express toll lanes to Lynnwood, which opened to the public in 2015. The long-term vision includes a 50-mile express toll lane system between SR 512 in Puyallup and the I-405/I-5 interchange in Lynnwood.

What to expect

Upcoming closures on SR 167 in 2025

Crews will install sign bridge, toll gantry, and cantilever structures over SR 167 in 2025. This complex work will require full and nightly closures of northbound and southbound SR 167. Crews will begin these closures starting as early as January 2025. These closures will ensure the safety of crews and the traveling public.
