The Transform 66 Project has reconfigured the Route 28 Interchange. The redesigned interchange improves traffic flow on both I-66 and Route 28, and adds express lanes access to/from Route 28.
The new design:
- Includes a new overpass reconnecting Braddock Road and Walney Road providing direct access to and from I-66, as well as to Route 28 to and from the south. (Opened November 2020)
- Improves traffic flow on Route 28 by removing traffic signals between Westfields Boulevard and Route 29 in Centreville. (Completed November 2020)
- Shifts access to the ballfields at Ellanor C. Lawrence Park to a new park access road from Stonecroft Boulevard north of the park. (Opened November 2019)
- Adds express lanes access to/from Route 28. (Opened November 2022)

Express Lanes Access at Route 28
Express lanes access at the Route 28 Interchange includes:
- A ramp from the westbound express lanes to the westbound general-purpose lanes, northbound and southbound Route 28, and Braddock Road/Walney Road
- A ramp from the eastbound express lanes to the eastbound general-purpose lanes, northbound Route 28, and Braddock Road/Walney Road
- A ramp from Route 28 northbound to the eastbound express lanes
- A ramp from Route 28 southbound to the westbound and eastbound express lanes
- A ramp from Braddock Road/Walney Road to the westbound express lanes. Drivers can access the eastbound express lanes at Stringfellow Road or by using the ramps from Route 28 North and South
Traffic Pattern Changes at the I-66/Route 28 Interchange
As part of the reconstruction of the I-66/Route 28 Interchange, the exit from I-66 East to Route 28 North was modified. It opened in September 2022, changing how drivers from I-66 East access Route 28 North and the Braddock Road/Walney Road exit.
- Drivers from I-66 East to Route 28 North will use the current flyover ramp to cross over I-66, then stay to the left at a new split and use new roadway to travel under the Braddock Road/Walney Road overpass, then merge with Route 28 North.
- Drivers from I-66 East to Braddock Road/Walney Road will use the current flyover ramp to cross over I-66, then stay to the right at the new split to join the ramp from Route 28 North to Braddock Road/Walney Road.
- Drivers from Route 28 North to Braddock Road/Walney Road will continue to stay to the left over I-66 and use the current left exit to Braddock Road/Walney Road.
- Drivers through the area on Route 28 North should be alert for vehicles merging from the left north of the Braddock Road/Walney Road overpass.
The new Braddock Road/Walney Road overpass over Route 28 opened in November 2020, reconnecting Braddock Road and Walney Road and allowing limited access to and from Route 28 and I-66. Additional traffic pattern changes were added during 2021 to allow additional movements and connections. Express lanes access has also been added.
The exit from I-66 West to Route 28 North and Braddock Road/Walney Road has been relocated approximately one-half mile prior to (east of) the old exit. The relocated exit opened in March 2022. The new exit location is immediately after the I-66 bridge over Stringfellow Road. The collector-distributor lane adjacent to I-66 West at the Route 286 (Fairfax County Parkway) Interchange will become the fourth travel lane where it enters I-66 West.

What Neighbors Can Expect
- Overnight construction activities will be avoided when possible. However, back-up alarms on equipment and trucks, which are necessary for the safety of construction crews, cannot be avoided at any time.
- Lighting of the construction area during the nighttime hours will be directed to minimize light pollution for nearby residents.
- Every effort will be made to communicate major traffic switches or nighttime work through project emails and the Transform 66 Outside the Beltway website.
What Drivers Can Expect
- Construction-related detours will be in place periodically.
- Drivers should slow down, stay focused, and be alert for construction crews.
