About the Project

Route 286

I-66 is being widened over the Fairfax County Parkway (Route 286) to add Express Lanes. There will not be direct Express Lanes access at this interchange. The new shared-use path will run to the north of the interchange along Fair Lakes Parkway, Fair Lakes Circle, and the ramp to I-66 West.

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

Construction Update

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

  • Fairfax County Parkway will remain open during construction, but there will be multiple traffic shifts and other traffic pattern changes during construction.
  • Drivers should expect additional changes as work progresses at the interchange. Sign up for project email updates to keep up to date.
