A developer, Vornado, has requested a Phased Development Site Plan (PDSP) to allow for redevelopment of the Rosslyn Plaza site- a 6.49-acre (282,801square feet) site located in the Rosslyn Station Area bounded on the north by 19th Street North, on the east by Arlington Ridge Road, on the south by Wilson Boulevard and on the west by N. Kent Street. There would be quite a dramatic change in that area with it being rezoned and part of Arlington Ridge Road being vacated. But of key interest here is the plan to build an area known as "The Promenade" along the route of 18th Street that would provide a pedestrian connection from the Mount Vernon trail to the east and the Metro station to the west.
The applicant is proposing a pedestrian passage through the site, conforming approximately to the alignment of 18th Street North. This passageway would connect to an envisioned bridge over I-66 to the Mount Vernon Trail
The project envisions a pedestrian and bicycle connection to the Mount Vernon Trail, via a bridge over Route 110, Interstate 66, and the George Washington Memorial Parkway. Its feasibility has not been determined, and will be discussed during the review of the PDSP.
Surely, this would require coordination with NPS and others.
This would certainly make for a more direct connection to Wilson Blvd and it's bike lanes as well as Rosslyn. And it could help to people to avoid the dreaded N,Lynn intersection. But then again, it's probably as pie in the sky as the tunnel under N. Lynn Street.
