About the Project

Route 50 Interchange

The Route 50 Interchange is being rebuilt and improved as part of the Transform 66 Outside the Beltway Project. The new interchange design will:

  • Add Express Lanes access to and from the east
  • Construct new Route 50 bridges over I-66 to improve traffic flow and create room for future mass transit
  • Add noise wall along the ramp from I-66 West to Route 50 West
  • Build a shared-use path through the interchange connecting Random Hills Park and Fairfax Corner with Fairfax Farms Road and points to the east

Get a closer look at what’s planned through the Transform 66 Interactive Map.

Beams have been installed for the new Route 50 bridges over I-66. The ramp from Route 50 West to I-66 West has been relocated to accommodate construction. Pavement has been placed approaching the new Route 50 West bridge. (April 20)

What Neighbors Can Expect

  • Noisy construction activities such as bridge demolition and pile driving will be avoided at night, when possible. Noise to expect at night includes back-up alarms on equipment and trucks, which is necessary to protect worker safety
  • Lighting of the construction work area will be directed to minimize light pollution for nearby residents
  • Project emails and website will be used to communicate major traffic switches or nighttime work

What Drivers Can Expect
