Nutley Street Roundabout Bypass Lanes with Direct Access to I-66 Now Open

About the Project

Route 50 Interchange

Route 50 Interchange

The Route 50 Interchange has been rebuilt as part of the Transform 66 Outside the Beltway Project. The new improved interchange design:

  • Has added express lanes access to and from the east
  • Constructed new Route 50 bridges over I-66 to improve traffic flow and create room for future mass transit
  • Added noise wall along the ramp from I-66 West to Route 50 West
  • Built a shared-use path through the interchange connecting Random Hills Park and Fairfax Corner with Fairfax Farms Road and points to the east

Route 50 Express Lanes Access

  • A ramp from eastbound Route 50 to the eastbound 66 Express Lanes.
  • A ramp from the westbound 66 Express Lanes to westbound Route 50.

Drivers will continue to have full access between Route 50 and the I-66 general-purpose lanes to and from the east and west.

New Route 50 Bridges

Route 50 traffic travels on new bridges in both directions over I-66. Route 50 East has been straightened approaching the bridge. 

New Combined Exit from I-66 East to Route 50 East and West

As part of the project, the exit from I-66 East to Route 50 East and West was combined. The new exit is approximately one mile prior to (west of) Route 50. The new exit location of Exit 57 A/B is immediately before the Monument Drive Bridge over I-66 and provides access to Route 50 East and Route 50 West. 

New Shared-Use Path

A new SUP has been constructed between the northeast quadrant of the interchange (near Fairfax Farms Road) and the southwest quadrant (near Random Hills Park) using four short tunnels and trail along Route 50 East. Fairfax County Park Authority is constructing a trail in Random Hills Park that will open in spring 2024 and connect to bicycle and pedestrian facilities on Random Hills Road.

What Neighbors Can Expect

  • Noisy construction activities 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
