True, but that's not the toll road. The toll roads are the outside lanes. I assume you never have to get off on Hwy 28 to Chantilly or Sterling. But it is called Dulles Toll Road and beyond that it is called Dulles Greenway which is also a toll. The purpose of the name change has to do with something with Loudoun County, VA funding that portion of the toll road. At one time, Loudoun County was the fastest growing county in the country. It's population grew by 96.9% from 1990 to 2000 and 84.1% from 2000 to 2010. Loudoun County is basically the spill over growth coming from Fairfax County, VA. I assume Loudoun County will get more growth now that the Metro's Silver Line is being extended to it along the Dulles Toll Road and the Dulles Greenway.
