The Alliance recommends constructing a new facility connecting the Loudoun County Parkway with I-66 and Rt 234 Business at Godwin Drive in Manassas. This roadway would provide an alternative to traffic from Route 28 between Manassas and I-66; to traffic from Route 234 Business to a more efficient link to I-66; and to and reduce cut-through traffic on Braddock, Pleasant Valley and Bull Run Post Office Roads in Fairfax County destined for eastbound I-66. The roadway would also provide a north-south alternative to Route 28 west of Dulles airport.
A Tri-County Parkway Location and Environmental Impact Statement Study was conducted between 2002 and 2005 to determine the best location for a new north-south corridor. Although technical studies showed the Tri-County Parkway alignment that appears on local comprehensive plans best met the documented purpose and need, the fact that the federal government stated that federal funding […]Read
Tri-County Parkway Overview
Since the late 1980’s the Tri-County Parkway has been planned as a secondary road much like the Fairfax County Parkway. Its alignment runs from the Prince William County Parkway/Route 234 Bypass west of Manassas near Godwin Drive, north through the northwestern sector of Fairfax County and southeastern Loudoun County to the Loudoun County Parkway, in essence linking the Manassas area in Prince William County to Washington Dulles International Airport and Route 7 in Loudoun County.
This alignment has appeared on the Fairfax, Loudoun and Prince William Comprehensive Plans since the early 1990s.
The original purpose and need for the Parkway included:
- Linking existing and planned communities in Northern Virginia’s three most populous counties.
- Providing an alternative to and diverting traffic from Route 28 between Manassas and I-66.
- Diverting traffic from Route 234 Business to a more efficient link to I-66.
- Providing an alternative to and reducing cut-through traffic on Braddock, Pleasant Valley and Bull Run Post Office Roads in Fairfax County destined for eastbound I-66.
- Providing a north-south alternative to Route 28 west of Dulles airport.

In November 2005, the Commonwealth Transportation Board selected the Bi-County Parkway over the Tri-County Parkway as the “locally preferred alternative.”
However on, May 18, 2011 the Commonwealth Transportation Board voted to create a new Northern Virginia North-South Corridor of Statewide Significance (CoSS) connecting Route 7 in Loudoun County with I-95 and Route 1 in Prince William County. The corridor will consist of a range of multi-modal options, including the long-planned Bi-County and Tri-County Parkways.
By its actions the Commonwealth Transportation Board scored an important victory for responsible, multi-modal planning, improved mobility, economic sustainability and the Washington Dulles International Airport.
Recent decades have seen state and local governments abandon one transportation option after another. It is no accident Northern Virginia has the nation’s third worst congestion.
The region can’t afford to give up one more.

Transportation planning is dispersed at multiple levels (state, regional, sub-regional, and local) and further by mode of travel. No one entity or level has ultimate responsibility for planning. More about transportation planning in the DC Metro Area.
