Route 29 (Lee Highway) Interchange in Centreville
The I-66 bridges over Route 29 (Lee Highway) in Centreville have been rebuilt as part of the Transform 66 Project. The new interchange design:
- Widens I-66 over Route 29 to create room for the 66 Express Lanes and future mass transit
- Widens Route 29 under I-66 for additional lanes to be added to Route 29 in the future
- Adds clearance to the Route 29 underpass for commercial vehicles

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.
- Drivers should expect additional changes as work progresses at the interchange. Sign up for project email updates to keep up to date.
