The project is being implemented in two distinct phases. Phase 1 extended Metrorail north and west from the East Falls Church station (Orange Line) by adding five new rail stations located in Fairfax County ending at the Reston-Wiehle East Station. Phase 1 opened for revenue service in July Phase 2 adds six Metrorail stations beyond to the Reston-Wiehle East Station three of which are located in Fairfax County: Reston Town Center, Herndon, and Innovation Center; and three of which are located in Loudoun County: Dulles Airport, Loudoun Gateway (Route 606) and Ashburn (Route 772). At this juncture, it is projected that Phase 2 will be open for revenue service in Development of the Metrorail Silver Line Phase 2 Extension project is a significant transportation capital improvement project for Loudoun County and the Washington Metropolitan Region. Civil construction activity for the Silver Line Phase 2 Extension ramped up significantly in 2016 and is expected to be sustained through To this end, staff plans to provide quarterly updates to the Board focusing on the construction activity in Loudoun County for the project for the Board s information and benefit. This update is limited to the Metrorail project and not associated with the adjacent construction capital projects (e.g., Croson Lane, Old Ryan Road to Ashburn Metrorail Station), which are reported to the Finance/Government Operations and Economic Development Committee (FGOEDC) on a quarterly basis.
