Metrorail milestones emerge in Tysons

By winter, left turns across Route 7 will only occur at signalized intersections

Traffic pattern changes, median closings and detours are on tap for Route 7 in Tysons Corner as construction of the Dulles Corridor Metrorail continues.

The break in the Route 7 median in front of Marshall’s Drive is closed, eliminating left turns into the Marshall’s shopping center. There crews are preparing to build the Tysons Central 7 Metrorail Station.

This is the first of several traffic pattern changes eliminating mid-block left turns along this stretch of Route 7 from the Dulles Toll Road to Route 123.

By winter, left-turns will only be allowed at signalized intersections: Tyco Road, Spring Hill Road and Gosnell/Westpark Drive.
On the northwest corner of Route 7 and 123, crews continue to prepare to build a 2,400 foot tunnel that will carry the rail from Route 123 to Route 7.

Meanwhile, drivers can see rail construction in two highly visible places: the Dulles Connector Toll Road and the Dulles Airport Access Highway between Wiehle Avenue and Reston Parkway.
