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

April – June 2018 Update

The SR 167 HOT lanes continue to operate well, although performance has struggled recently with the ongoing construction of the 167-405 Direct Connector. The construction project expects to conclude in 2019, providing significant relief for traffic. The southbound extension continues to be difficult to manage because the bottleneck in the southern end of the corridor creates enough congestion that spills into the back-up stream, causing occasional congestion in the HOT lane. WSDOT made multiple changes to the algorithm in response and will continue to monitor the situation closely.
