SR 99 Targeted Corridor Study

English  |  Español  |  한국어

Welcome!

WSDOT is developing a plan to identify near-and medium-term transportation improvements for the State Route 99 (SR 99) corridor from 168thStreet Southwest to Airport Road.

SR 99 in unincorporated Snohomish County is a heavily traveled corridor that serves as a major north-south alternative to I-5, and links Lynnwood, Everett, and other growing communities in Snohomish County. Community Transit operates the Swift Blue Line Bus Rapid Transit service along the corridor, which provides high frequency bus service between Shoreline and Everett, and additional transit improvements are being planned along the corridor.

WSDOT is also developing a project along SR 99 from 148th Street to Airport Road that will convert the outside shoulders to Business Access Transit (BAT) Lanes. BAT lanes are curb lanes used only by right-turning vehicles and buses. They help buses move more efficiently through traffic and provide better access to businesses. The project will also consider active transportation and multi-modal safety improvements. Your feedback will help to inform the scope of this project.
