New Route 50 Bridges
Route 50 traffic travels on new bridges in both directions over I-66. Route 50 East has been straightened approaching the bridge.
New Combined Exit from I-66 East to Route 50 East and West
As part of the project, the exit from I-66 East to Route 50 East and West was combined. The new exit is approximately one mile prior to (west of) Route 50. The new exit location of Exit 57 A/B is immediately before the Monument Drive Bridge over I-66 and provides access to Route 50 East and Route 50 West.
New Shared-Use Path
A new SUP has been constructed between the northeast quadrant of the interchange (near Fairfax Farms Road) and the southwest quadrant (near Random Hills Park) using four short tunnels and trail along Route 50 East. Fairfax County Park Authority is constructing a trail in Random Hills Park that will open in spring 2024 and connect to bicycle and pedestrian facilities on Random Hills Road.
