Relocated Exit from I-66 West to Route 28 North and Braddock Road/Walney Road Now Open
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 the morning of March 22. The new exit location is immediately after the I-66 bridge over Stringfellow Road and will be the permanent location for this exit. Additionally, the right lane on I-66 West over Route 286 (Fairfax County Parkway) was closed and will remain so through August 2022 to allow for continued construction. The collector-distributor lane adjacent to I-66 West at the Route 286 Interchange will become the fourth travel lane when it enters I-66 West.
Route 28 South traffic shifted to the new bridge over I-66 in October 2021. After the shift, demolition of the old Route 28 South bridge deck and piers began, which was followed by removal of the two bridge abutments. Demolition of the old Route 28 South bridge was completed by mid-December 2021. Learn more.
New Ramp from Route 28 South to I-66 East Now Open on Left Side of Route 28
Current loop ramp on right side will remain closed until early 2022
A new ramp from Route 28 South to I-66 East opened in April 2021. Drivers on Route 28 South stay to the left to access I-66 East using the new ramp. Drivers from the Braddock Road/Walney Road Bridge headed to I-66 East can access this new ramp or continue farther south to the exit to Route 29 North, stay to the right to Route 28 North, then stay to the right and follow signs to I-66 East.
The loop ramp from Route 28 South to I-66 East will open permanently later in the project.
New Braddock Road/Walney Road Overpass Now Open with Direct Access from I-66 West and Route 28 North via New Ramps
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 will be added later in the project.
