The authority’s priority list describes the total project to realign Metro’s Blue Line as one that would bring a new Blue Line station in Rosslyn to allow more trains through on all three lines. While the station could be built separately at first, the long-term plan over coming decades would be to continue the tracks through a new tunnel under the Potomac River to Georgetown, where the line would turn along M Street toward Union Station. The new Rosslyn Station could have a connection allowing riders to walk between the Blue Line and Orange and Silver Line platforms.
Metro is also separately applying to NVTA for $94.7 million more to continue power upgrades that could eventually allow all Blue and Orange Line trains to be eight cars long at rush hour.
