Express lanes schedule

I-5 Express Lanes in SeattleWSDOT uses the I-5 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.
