Route 29 Interchange in Centreville

The I-66 bridges over Route 29 in Centreville are being demolished and rebuilt as part of the Transform 66 Project. The new interchange design will:

  • Widen I-66 over Route 29 to create room for Express Lanes and future mass transit
  • Widen Route 29 under I-66 for additional lanes to be added to Route 29 in the future
  • Add clearance to the Route 29 underpass for commercial vehicles

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

Long-term Closure of Ramp from Route 29 North
to I-66 East Begins Jan. 16, 2020

The left-turn lane and ramp from northbound Route 29 to I-66 East will close for approximately four months beginning on or about Thursday night, Jan. 16.

Drivers on Route 29 North will be directed to stay to the left and continue to the intersection at Trinity Parkway/Machen Road. At the traffic signal, drivers will use the left-most turn lane only to make a U-turn onto Route 29 South, then stay to the right and follow signs to I-66 East.

As an alternate route to I-66 East, drivers can continue north on Route 29 to Route 28 North (1/2 mile), stay to the right and follow signs to I-66 East.

As an alternate route to Trinity Parkway, drivers can continue north on Route 29 to the next traffic signal (1/4 mile) and turn left on to Trinity Parkway. 

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

  • Route 29 will remain open during construction, but there will be numerous long-term and short-term ramp closures, traffic shifts, and other traffic pattern changes during construction.
  • The ramp from Route 29 South to I-66 West will be closed for about 18 months beginning Oct. 28, 2019. The ramp will be rebuilt to fit the new I-66 bridges. Southbound Route 29 traffic will use two left turn lanes to access I-66 West. Learn more.
  • Drivers should consider alternate routes when possible.
  • Drivers should expect additional changes as work progresses at the interchange. Sign up for project email updates to keep up to date.
