DC Metro Studies Options for Future Needs


On June 17, DC Metro announced the launch of a two-year study of the Blue, Orange and Silver lines with the goal of identifying long-term options to improve reliability, meet future ridership demand, and better serve customers.

Today, the Blue, Orange and Silver (BOS) lines all share a single set of tracks between the Rosslyn tunnel and the Anacostia River, creating a bottleneck that limits the number of trains that can cross between Virginia, Maryland, and the District of Columbia. The limited capacity means that Metro cannot easily add more trains and has limited ability to work around service disruptions. With the current configuration, a disruption on one line can have a ripple effect on all three lines.

The BOS Study will identify potential infrastructure improvements and service alternatives to resolve these issues.

“Our rebuilding efforts and ongoing preventive maintenance have improved Metro’s reliability to the highest levels in eight years, but it’s time to start thinking about the Blue, Orange and Silver lines’ infrastructure constraints so that Metro is well positioned to serve future generations,” said Metro General Manager Paul J. Wiedefeld.

The first phase of the study will assess key issues and trends and document why improvements to the Blue, Orange, and Silver lines are necessary. Subsequent phases will include the development and evaluation of alternatives, as well as a thorough analysis of costs and benefits, with recommendation of a preferred alternative expected to occur by the fall of 2020.

Ultimately, the study will identify and analyze a range of potential alternatives before recommending a “locally preferred alternative” to move forward with federal environmental review, full design, and competition for federal funding. Over the next two years, Metro plans extensive outreach to engage the community, stakeholders, and transit experts to gather feedback and make recommendations.

Among the options being considered, according to, is building a new tunnel under the Potomac to extend the Blue Line, including a new station in Georgetown.
