The Metropolitan Transportation Commission (MTC) is working with Caltrans, the California Highway Patrol and county congestion management agencies to create a network of Express Lanes, also known as high occupancy toll (HOT) lanes, throughout the Bay Area. Express lanes allow solo motorists to bypass congestion for a fee while carpools and buses use the lanes free of charge. Tolls vary with congestion levels to keep the lanes free-flowing. The regional Express Lane Network will be developed by converting existing carpool lanes to express lanes and constructing new lanes to close gaps in the system. The ultimate objective is to have a seamless, integrated network of 570 miles of express lanes by 2035. For information on express lanes currently in operation, visit:
