This project, in cooperation with Fairfax County, will provide an important new link to Route 123 over the Capital Beltway (I-495) for commuters and visitors to Tysons. The link will improve local traffic and access for drivers, as well as provide a vital option for area bicyclists and pedestrians.  

The half-mile project includes new roadway from the interchange of the I-495 Express Lanes and Jones Branch Drive to Scotts Crossing Road. Improvements will also be made along the access road from Jones Branch Drive to the Express Lanes, as well as along Scotts Crossing Road. Project features include:

  • Two travel lanes and on-street bike lanes in each direction
  • Three bridges over the I-495 Express and general-purpose lanes
  • 8- to 12-foot-wide lighted sidewalks, landscaping and other streetscape amenities
  • A wide, raised median to accommodate the future transit bus

Estimated Costs
Preliminary Engineering: $6.1 million
Right of Way Acquisition and Utility Relocation: $2.8 million
Construction: $51.3 million
Total: $60.2 million

The project is being completed through a combination of federal, state and county funds. Fairfax County led design and development, while VDOT is administering construction.


By providing an alternate route across the Beltway and linking the Tysons East and Central areas, the Connector is expected to relieve traffic along Route 123, at the I-495 interchange, and at other congested intersections. The road is expected to carry more than 32,000 vehicles per day by 2040.
