The Transform 66 Project will reconfigure the Route 28 interchange to add Express Lanes access and improve traffic flow on both I-66 and Route 28. The project will remove the four sets of traffic signals on Route 28 between Westfields Boulevard and Route 29, as well as build a new overpass to reconnect Braddock Road and Walney Road.
The new design:
- Adds access to and from the future express lanes from Route 28. (Opens December 2022.)
- Removes traffic signals on Route 28 between Westfields Boulevard and Route 29 in Centreville. (Rolling basis, complete by late 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 on Nov. 13, 2019.)
- Builds a new overpass reconnecting Braddock Road and Walney Road (opens late 2020) providing direct access to and from I-66, as well as to Route 28 to and from the south.
Get a closer look at what’s planned through the Transform 66 Interactive Map.
Overnight Lane and Ramp Closures for Braddock-Walney Bridge Construction Begin August 6
UPDATE (8/10): This work will continue Tuesday, August 11, through Thursday, August 13.
Between 9 p.m. and 5 a.m. on Monday night, August 3, through Thursday night, August 6, Route 28 will be reduced to a single travel lane in each direction for about one mile to accommodate installation of beams for the new Braddock Road/Walney Road Bridge. Two-way traffic will run on Route 28 North so that crews can safely install bridge beams over the southbound lanes of Route 28.
Other closures necessary during this time include: the ramps from Route 28 South to I-66 East and West, the ramp from I-66 East to Route 28 North, and Braddock Road near Route 28. Detours will be posted. Drivers should expect delays if traveling in this area.
Planned traffic impacts on Route 28:
- Around 9 p.m.: The right-most lanes of Route 28 South and left-most lanes of Route 28 North will close between E.C. Lawrence Park Athletic Fields and Route 29.
- Around 10 p.m.: Route 28 South traffic approaching Braddock Road will be narrowed to a single lane on the left. Traffic will cross through a gap in the median barrier to continue traveling south on the Route 28 North side of the roadway and will remain in this pattern until south of I-66. Southbound traffic will then cross back over to the Route 28 South side of the roadway and resume normal travel.
- Around 10 p.m.: Route 28 North traffic approaching I-66 will be narrowed to a single lane on the right and remain in this pattern past Braddock Road/Walney Road. Northbound traffic will resume normal travel following the point where southbound traffic crosses over to Route 28 North.
- Between 10 p.m. and 5 a.m.: Two-way traffic on Route 28 North will be separated by traffic barrels and one closed travel lane. State police will be on-site to assist with traffic control and response.
- All lanes will reopen by 5 a.m. daily.
Detour for ramp from Route 28 South to I-66 West
- The ramp will be closed.
- Traffic will be detoured farther south to Route 29 South, follow signs to I-66 West and make a left at the traffic signal to access I-66 West.
Detour for ramp from Route 28 South to I-66 East
- The ramp and two left turn lanes from Route 28 South to I-66 East will be closed.
- Traffic will be detoured farther south to Route 29 North, stay right for Route 28 North, then follow signs to I-66 East.
Detour for ramp from I-66 East to Route 28 North
- The ramp will be closed.
- Traffic will be detoured farther east to Route 286 (Fairfax County Parkway) North, stay to the right for I-66 West, then follow signs to Route 28 North.
Detour for Braddock Road between Newton Patent Drive and Route 28
- Braddock Road will be closed between Newton Patent Drive and Route 28.
- Traffic will be directed to Westfields Boulevard to access Braddock Road and/or Route 28.
New Fly-over Ramp from I-66 East to Route 28 North
The first new exit ramp and bridge for the under-construction I-66 and Route 28 Interchange opened ahead of schedule on Wednesday, July 8. Drivers on I-66 East will exit to Route 28 North using the new flyover ramp, located prior to Route 28 and the old loop ramp. The new ramp was completed as an early interim milestone for the I-66 Outside the Beltway Project, and is the first of several permanent traffic pattern changes happening this year at the I-66 and Route 28 Interchange area.
The old loop ramp has closed permanently to allow for construction of new northbound Route 28 thru-lanes and additional ramps for the redesigned interchange. Route 28 North traffic patterns have been shifted temporarily to accommodate the new traffic movement until future traffic shifts occur later in 2020. Drivers should use caution and follow roadway signs when traveling in this area.

What Neighbors Can Expect
- Overnight construction activities such as bridge demolition and pile driving 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.
- Detours will be in place for extended periods of time to allow for construction.
- Small-charge dynamite operations continue around the interchange to break up underground rock. Blasting activities generally occur between 11 a.m. and noon, are closely coordinated with safety regulators, and utilize seismic monitoring. Pre-blast structural surveys have been offered for nearby buildings. Contact FAM Construction for more information on these surveys.
- 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.
- New traffic patterns will be implemented as construction progresses.
- Drivers should slow down, stay focused, and be alert for construction crews.
- Drivers should expect additional changes as work advances at the interchange. Sign up for project email updates to keep up-to-date.
- Traffic stoppages will happen regularly around the interchange between 11 a.m. and noon to accommodate underground blasting.
- Walney Road will be closed between Route 28 and Cabells Mill Drive through late 2020 while the new Braddock-Walney connector bridge is built. Drivers will be temporarily detoured to Westfields Boulevard to access Walney Road from Route 28. Access to Route 28 North from Walney Road will be permanently directed to Westfields Boulevard.
