The momentum is growing for using tollroads, particularly with tolls that vary according to the amount of traffic (congestion pricing), to solve urban congestion problems. New congestion-priced toll roads in Minneapolis and Denver have joined such roads in California, and plans are underway to open more in many other cities and states.
In most cases, the revenue from the tolls goes to pay for the roads. In some cases, a regional tollroads authority collects the tolls and uses them to construct new roads and maintain the existing ones.
