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.

April – June 2017 Update

The SR 167 HOT lanes continues to operate smoothly and successfully. The biggest change in the last few years was extension of the system 5 miles in the SB direction, which opened in December 2016. This significant change has eased traffic congestion in the area (especially near the SR 18 interchange), generating an increased number of tolled trips, and increased revenue. The pubic has responded positively to the project, although concerns remain about how to terminate a HOT lane into a general purpose lane. The congestion at this terminus creates some performance concerns at certain times during the day.
