How do Express Lanes and Managed Lanes Work
Express lanes and managed lanes are typically built within an existing highway. They often add capacity to the highway to accommodate more traffic to relieve congestion. However, unlike other toll roads, the price changes based on the level of traffic on the parallel free road. The tolls vary based on congestion and are not known before you travel.
