A new traffic pattern will be implemented on or about Monday, Oct. 28, at the I-66/Route 29 Interchange in Centreville. The change is expected to last approximately 18 months. Traffic changes include closing the ramp from Route 29 South to I-66 West, and installing new, temporary left-turn lanes at the existing traffic signal to allow drivers access to I-66 West. Changes are needed to rebuild the I-66 bridges over Route 29 to allow for future mass transit expansion along I-66 and future widening of Route 29 under the interstate.
- The loop ramp from southbound Route 29 to I-66 West will close. Drivers will access I-66 West by using two new left turn-only lanes at the traffic signal slightly farther south that will join the existing ramp from northbound Route 29 to I-66 West.
- Drivers traveling north on Route 29 to the ramp to I-66 West should be alert for Route 29 South traffic entering the ramp from the left.
Drivers should expect construction-related detours and additional changes to traffic patterns as work progresses at the Route 29 Interchange. Drivers are reminded to use caution and pay attention to lane markings and roadway signs in construction work zones.
When complete, the Transform 66 Outside the Beltway Project will feature three general purpose lanes and two Express Lanes in each direction from I-495/Capital Beltway to Route 29 in Gainesville. The I-66 Outside the Beltway Express Lanes are expected to open in December 2022.
