More work on the Dulles Corridor Metrorail Project means more road changes.
Drivers who used Route 123 to Route 7 westbound toward Reston and Wolf Trap will now have to access Route 7 from a new exit.
the exit is located just south of International Drive and the Marriott Courtyard Hotel. It will take you to Frontage Road and you'll turn right onto Route 7 West.
If you miss the new ramp, you'll have to continue south on 123, turn right on Old Courthouse Road which will eventually intersect with Route 7 in both directions.
There will be signage helping to direct traffic. The detour will be in place for the next four months.
