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.

New Bridge on Route 50 East Over I-66 is Now Open

Traffic on eastbound Route 50 shifted to a new bridge over I-66 on Saturday, July 17. This new, permanent bridge is located slightly east of the current bridge, which will be demolished following the traffic shift. Learn more.

Demolition of Route 50 Bridges over I-66 Has Begun

Continued demolition of the old Route 50 East bridge over I-66 will require all lanes of I-66 West approaching Route 50 to close nightly between Tuesday, July 27, and Sunday, August 1. The I-66 West ramps to/from Route 50 will also be closed. Traffic will be detoured using Route 50 and Route 608 (West Ox Road).

Some demolition activities will generate unavoidable noise and other disruptions. The following measures will be taken to minimize impacts as much as feasible:

  • Concrete will be hauled away to be processed off-site
  • Work area lighting will be directed toward roadway and away from residences
  • Dust control measures will be in place
  • Construction vibrations and noise will be monitored

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
