Express lanes are not the same as regular toll roads. Regular toll roads charge a fixed rate. Different tolling methods are used on express lanes (static, time of day and dynamic) to manage congestion and may vary based on traffic conditions. With static tolling, the toll rate in the express lanes is set to an amount that does not change. With time of day tolling, the express lanes toll rate is only charged during specific peak travel periods. When dynamic tolling is used, the express lanes toll rate increases as traffic builds in the express lanes and decreases as traffic reduces.
