Loudoun County residents are telling Virginia’s utility watchdog that tolls on the Dulles Greenway are too high and are pushing drivers to other clogged roads.

The Virginia State Corporation Commission, which regulates state utilities and the privately owned 14-mile Greenway, is holding public meetings in Loudoun to determine whether the tolls, which can reach $5.90 for a trip down the length of the road during rush hour, are discouraging drivers from using the road — a violation of state law.
