I-5 and I-90 Express Lanes

View of Express Lanes

WSDOT uses the I-5 and I-90 express lanes to assist the flow of traffic during busy travel times. These lanes are scheduled to move in the direction that will relieve the most congestion from the transportation system. We operate the lanes on a typical daily schedule that changes on the weekends and occasionally for major events

Game Day Congestion

  • Many traveling to events in Seattle wonder why, on workdays, we don't adjust the express lane schedules drastically to accommodate the increase in drivers traveling to Seattle. Recent traffic studies provide the answer.
