WASHINGTON: HOT Lanes on SR 167 in the Puget Sound Region

The Puget Sound Regional Council of Washington State estimates that by 2030, 45% of the core freeway system in the Seattle metropolitan area will be congested. The State Route (SR) 167 High-Occupancy Toll (HOT) Lanes Pilot Project converted the existing HOV lanes on SR 167 within King County/Seattle, Washington to HOT lanes, from Southwest 15th Street in Auburn to I-405 in Renton without expansion of the existing freeway. This four-year pilot project will evaluate the ability of the HOT lane concept to manage congestion and generate revenue. During the four-year pilot, the facility's performance, socioeconomic impacts, and public interest/acceptance of the facility will be assessed on an annual basis.

Project Status

Open to Traffic

October – December 2017 Update

The SR 167 HOT lanes continue to operate smoothly and successfully, although performance on the lanes has deteriorated recently. The biggest change during the last few years was an extension of the system for five miles in the SB direction, which opened in December 2016. This change benefited the northern part of the corridor, but created challenges for the southern terminus. The northbound terminus experienced similar challenges. WSDOT made adjustments to the algorithm and is evaluating additional refinements to improve operation.
