New Blue Line Connections Revisited
A recent Metro study determined that a Rosslyn bypass is infeasible but a second Metrorail station in Rosslyn to restore frequent peak period Blue Line service is possible.
In a post last year describing the strategies in Metro 2025, we described some options for new Blue Line connections. The first was a Rosslyn bypass that would allow some Blue Line trains to connect directly to the Orange Line at Court House. The second was a second Rosslyn station that would connect to the current Rosslyn station via an underground walkway. Both of these options, illustrated in the graphics below, would allow increased frequencies on the Blue Line during peak periods.
Metro recently completed a study that evaluated these two options (pdf). The bad news is that the Rosslyn bypass (interline connection) was deemed infeasible. This is due to the location of building foundations and the turning radius required by the track.
However, the second Rosslyn station was deemed feasible, as illustrated in the map below.
This new Metrorail station would connect to the current Rosslyn station via one underground walkway.
Metro Office of Planning is submitting the second Rosslyn station for project development funding.
