Tysons Corner is serviced by four metro stations between the Dulles Connector Road and the Dulles Toll Road. The Dulles Corridor Metrorail Project consists of two stations along Route 123, McLean and Tysons Corner, and two in the median of Route 7, Greensboro and Spring Hill. These two major highways are connected by two 1,400 foot tunnels that run under the highest natural point in Fairfax County. This tunnel was constructed by the New Austrian Tunneling Method.
The blue and yellow horizontal cranes used in Phase 1 will not be a be a part of Phase 2 as the segments will be constructed using a different method.
The Silver Line stations in Tysons Corner opened on July 26, 2014. Final road paving along Route 7 and intersecting roads will be taking place during Spring 2015.
