• Option A: Run the Blue Line between Franconia-Springfield to the new “Rosslyn II” station only.
• Option B: Build a new track connection between Arlington Cemetery, “Rosslyn II,” and Court House Station. This would permit some trains to offer one-seat rides between Tysons, Rosslyn-Ballston, Pentagon, Crystal City/ National Airport, and Franconia-Springfield.

Concept: Build a new “Rosslyn II” station with a direct pedestrian link to the existing Rosslyn station. Extend the Blue Line service through a new tunnel under the Potomac River into DC and Maryland.

A new, adjoining station with a new tunnel under the Potomac River would separate the three lines at Rosslyn, provide new capacity across the Potomac, and allow for different service patterns:

• Option A: Blue Line service would run from “Rosslyn II” to Georgetown, Mid-City DC, and Union Station, then continue through Northeast DC into Prince George’s County.
• Option B: Blue Line service would run from the “Rosslyn II” station through Georgetown and along or near Wisconsin Avenue to connect with the Red Line at Friendship Heights or Bethesda.

Concept 5 - New Silver Line connections north of I-66

Concept: Provide new Silver Line service through a new tunnel under the Potomac River into DC and Maryland, north of I-66.

A new tunnel under the Potomac River would provide a new Silver Line “corridor” north of I-66 that could operate as local service, express service or a mix, with different service options:

• Option A: Operate new Silver Line service between West Falls Church, Mid-City DC, Union Station, Northeast DC and Prince George’s County.
• Option B: Similar to Option A, but Silver Line service would operate from McLean instead of West Falls Church.
• Option C: Operate new Silver Line service between Tysons, Bethesda or Friendship Heights, northern DC and Prince George’s County.

Concept: Provide new Silver Line service through a new tunnel under the Potomac River into DC and Maryland, south of I-66.

A new tunnel under the Potomac River would provide a new Silver Line “corridor” south of I-66 that could operate as local service, express service or a mix, with different service options:

• Option A: Operate new Silver Line service from West Falls Church along Route 7 and Columbia Pike, then across the Yellow Line Bridge to Southeast DC and Prince George’s County.
• Option B: Similar to Option A, but the Silver Line would turn southward to Crystal City and National Airport rather than heading to DC.
