Background – Bi-County Parkway's Need and Official Standing Well-Documented 

Over the next 30 years, Loudoun and Prince William Counties will add 300,000 new jobs and have a combined population of 1.2 million. Today, there are 200,000 north-south vehicle trips a day in the region, which will grow to nearly 400,000 trips by 2040.

The Bi-County Parkway’s (BCP) need and benefits are well-documented by a recent Draft Environmental Impact Statement (EIS) as well as several local studies.

The 2005 Draft Bi-County/Tri-County Parkway EIS and Location Study said, “This (bi-county) corridor affects the largest decrease in hours of delay over the no build alternative.” It also ranks second in alternatives studied in reducing vehicle miles of travel.

Official Standing
The Bi-County Parkway:

  • Has appeared on Loudoun and Prince William County master plans for years.
  • Appears in the Northern Virginia Transportation Authority’s TransAction 2040 regional plan, the National Capital Regional Transportation Planning Board’s (TPB) 2040 fiscally Constrained Long Range Plan and the Commonwealth of Virginia’s statewide long range plan. 
  • Is located within and is a key component of Northern Virginia’s North-South Corridor of Statewide Significance created and designed by the Commonwealth Transportation Board in 2011.
  • Was selected in 2006 by the Commonwealth Transportation Board (CTB) as its preferred alternative. To read the CTB resolution, click here.

Private Sector Support
The BCP commands broad support with Northern Virginia’s private sector, which recognizes its importance in connecting Northern Virginia (and Virginia’s!) second and third largest counties as well for the improved access it provides to Washington Dulles International Airport.

The Bi-County Partnership is a coalition formed to increase public awareness of the importance and benefits of the BCP. The Partnership consists of the Loudoun County Chamber of Commerce, Prince William Chamber of Commerce, Dulles Regional Chamber of Commerce, Committee for Dulles, Dulles Area Transportation Association, Dulles South Alliance, Washington Airports Task Force and the Northern Virginia Transportation Alliance.

Most Immediate Need
To secure federal sign-off and favorable record of decision on the Draft Environmental Impact Statement that was essentially completed in 2005 and has been a political football for more than eight years.
