    What's Being Done

    In 2011, the U.S. Army relocated about 8,500 jobs to Fort Belvoir North Area and 6,400 jobs to the Mark Center in Alexandria as part of the Base Realignment and Closure (BRAC). These jobs increased traffic on area roads.

    Once the BRAC relocation was complete, there are a total of approximately 43,000 jobs at Fort Belvoir, the Fort Belvoir North Area and the Mark Center .  The influx of employees increased the traffic on I-95, Route 1 and the Fairfax County Parkway.

Project Benefits

Fairfax County Parkway

The Fairfax County Parkway Extension, from Rolling Road to Fullerton Road, opened early to accommodate increased traffic. When the first two phases of this four-phase project opened in September 2010, motorists gained a direct route to I-95 through the Fort Belvoir North Area in Springfield. The Virginia Department of Transportation (VDOT) provided partial funding for the project, acquiring the necessary right-of-way, and will maintain the road. The Federal Highway Administration administered the final design and construction. The United States Army provided the right-of-way through the Fort Belvoir North Area, formerly the Engineer Proving Ground.

Project Phases

  • Phase 1 - Construction of a four-lane section between Rolling Road and Fullerton Road that provides direct access to I-95.  Cost is $98 million. Construction began in November 2008 and was finished in September 2010.

  • Phase 2 - Construction of a partial cloverleaf interchange at Rolling Road and the Fort Belvoir North Area entrance. Extension of Boudinot Drive to provide an on-ramp to the southbound parkway. Construction began November 2008 and finished in September 2010.

  • Phase 3 - Relocates Hooes Road and Rolling Road with improvements to the Franconia-Springfield Parkway interchange and the Fairfax County Parkway. Construction began in November 2010, and was completed by summer 2012.

  • Phase 4 - Extended Boudinot Drive at the Fairfax County Parkway linked with a loop ramp.  Phases 3 and 4 cost $50 million. Construction of Phase 4 began in July 2009 and was completed in July 2011.

Pedestrian and Bicycle Trail

  • Along this new section of the Fairfax County Parkway there is a multi-purpose trail for jogging, walking and biking. Currently, most of the trail is completed except for the section near the Rolling Rd. overpass which opened in April 2012. Cyclists can now access the current trail that runs all along the Fairfax County Parkway.

Saratoga Park & Ride Lot

  • I-95 commuters heading to the Tysons Corner now have another park-and-ride option with the Saratoga commuter parking lot which opened in late 2012. The 535-space lot, located at Barta Road and the Fairfax County Parkway, is equipped with bus bays, and  bicycle and pedestrian facilities. Located off of the new Fairfax County Parkway extension, This lot provides easy access to I-95. In addition, an express bus line will start at the lot, and make local stops before accessing the 495 Express Lanes to Tysons Corner. Read more on the Tysons Express bus route.

Mark Center (BRAC 133) Access Study

The purpose of this Mark Center Access Operational Analysis is to enhance transportation access to Mark Center, meet the existing and future traffic demands of the projected 7,000 new employees which relieves anticipated congestion to the I-395/Seminary interchange and surrounding local roadway network and provides opportunities for planned transit uses.

The findings of this report will be used during the next stages of project development that include the Final Interchange Justification Report and National Environmental Policy Act evaluation. View the Mark Center Access Study public comments here.

I-95 Access Ramps to Fort Belvoir North Area

The Federal Highway Administration is administering the construction of a new access ramp from I-95 reversible High Occupancy Vehicle (HOV) lanes directly to the Fort Belvoir North Area. Construction of the I-95 south ramp began in January 2010, and was completed in December 2010. These ramps will provide additional access points for 8,500 employees. The new ramps will also provide an alternative access point to the I-95/Fairfax County Parkway interchange. Construction started on a ramp from the 95 Express Lanes to Fort Belvoir North Area in summer 2012, and was completed in late 2014 when the 95 Express Lanes opened. The access ramps project brochure provides more information.
