Where: The 14-mile highway connects Dulles International Airport and Leesburg.
History: Dedicated in September 1995, it was the first private toll road in Virginia since 1816. Planning started in 1988 after the General Assembly authorized private development of toll roads.
Tolls: Fees increased in September. Drivers pay as much as $2.75 to drive the full length during the busiest times and $2.35 at other times. Tolls could rise as high as $3 by 2007.
Advantage: The 65 mph speed limit and absence of traffic lights give commuters an alternative to congestion on Routes 7 and 28. Greenway operators estimate it saves at least 15 minutes at rush hour on the trip from Leesburg to Dulles.
Expansion: Plans include widening the highway from Leesburg to Claiborne Parkway in Ashburn and building two exits in between, expanding the main toll plaza, building a ramp to the airport and reconfiguring an exit at Route 606 as a cloverleaf.
