Metro has released the results of a pivotal study of options for increasing capacity of the Metrorail system, and the preliminary conceptual designs suggest big transit changes might eventually be coming to Arlington.
Among the ideas floated by the transit agency are a second Rosslyn Metro station, a new tunnel under the Potomac, and an new stretch of the Silver Line to either run down Columbia Pike or through North Arlington.
Metro says its “Blue/Orange/Silver Capacity & Reliability Study” is necessary because the existing Rosslyn tunnel is a bottleneck for all three lines, producing delays and crowding that will only get worse — particularly in Arlington — due to expected population and job growth.
The study is intended to “identify the best and most cost-effective solutions to address future ridership, service, and reliability needs on these Metrorail lines,” Metro said. “The approval of dedicated funding from Metro’s jurisdictional partners provides funding to bring the existing system into a state of good repair and keep it well maintained going forward; however, there are future transportation needs that we must begin addressing now.”
Among the changes being considered are:
- A second Rosslyn Metro station, with a pedestrian connection to the current station.
- A second tunnel across the Potomac.
- A Blue Line extension to run from Rosslyn through Georgetown and upper Northwest D.C., and into Montgomery County.
- A Blue Line extension to run from Rosslyn through Georgetown and mid-city D.C., and into Prince George’s County.
- A new urban core loop “connecting Pentagon, Rosslyn, Georgetown, the Dupont and Shaw neighborhoods, and the Navy Yard/Waterfront area.”
- New “NoVa Circulator” option that will route some trains from the Pentagon, around Rosslyn and down the Orange/Silver line toward Courthouse.
- A Silver Line extension down Columbia Pike and up Route 7, connecting with the West Falls Church Station.
- A Silver Line extension north of I-66, through North Arlington and McLean.
Major capital projects like a Metro line extension would take several decades and the cost is only described as “high.”
The idea of running Metro down Columbia Pike was discussed while debate raged over the since-canceled Columbia Pike streetcar project, and might find some public support, but the concept of Metro running through mostly residential North Arlington seems much more politically infeasible. Wherever a new Metro line runs, big changes, development and a rise in property values can be expected, as happened with the original construction of the Metrorail system in Arlington.
A number of comparatively minor changes are also proposed, like pocket tracks, crossovers and turnarounds to better mitigate delays and incidents, reconfiguring train seats to provide more space, and adding new station entrances.
Metro says it is now embarking on a public engagement process, with a goal of selecting a set of “locally-preferred” options, both long- and short-term, by next fall.
A public open house is planned in Arlington next week, to be held Monday from 4:30-7:30 p.m. at George Mason University’s Van Metre Hall (3351 Fairfax Drive) in Virginia Square.
