The lane is open during peak travel times, mostly on weekends and holidays. When not open to traffic, the lane is used as an emergency shoulder for vehicle breakdowns and emergency services. Tolling began in 2022, and drivers will be billed for using the Express Lane either through their license plate or ExpressToll pass/transponder.
