Drivers on Rt. 7 near Tysons Corner will notice permanent changes to traffic patterns that will allow for construction of a Tysons Central Metrorail station. The Tysons Central station is part of the new line that will serve the Dulles Metrorail Project. Tysons Central station construction is scheduled to end in 2013.

According to the Washington Post:

"The changes are at the intersection of Route 7, Marshalls Drive (the road leading to the Marshalls store) and the frontage road. Traffic from Marshalls Drive and the frontage road onto Route 7 is now only allowed to turn right. Drivers may not turn from Marshalls Drive to westbound Route 7, nor from the frontage road to eastbound Route 7. Additionally, drivers on Marshalls Drive or the frontage road may not cross Route 7."
