Metroway has been expanded since its opening in 2014, both in number of stations and length of route. Two new stations opened in Arlington, both in April 2016. Fayette station in Alexandria opened in 2017. While the Fayette and 33rd & Crystal stations are infill stations along the existing route, the addition of the Pentagon City station extended the route north, which changed the northern terminus from Crystal City to Pentagon City. The 33rd & Crystal stop offers two-way service, while Pentagon City, the new northern terminus, is southbound-only. The National Capital Region Transportation Planning Board wants to extend the dedicated transitway in Crystal City North to the Pentagon City Metro station. Beginning May 25, 2019, as a result of the Blue and Yellow Lines being shut down south of National Airport for the summer, new stops were added on Potomac Avenue at East Glebe Road near the Kaiser Permanente and the National Institute for the Blind (NIB) Headquarters. As part of the Amazon HQ2 project, plans were made in 2019 to extend the dedicated transitway to the section between Crystal City and Pentagon City, and add new stops at 12th & Clark Street, 12th & Elm Street, 12th & Hayes Street, and Army-Navy Drive. Construction began in April 2022, with completion expected in April 2023. ==Changes==

As part of WMATA's Better Bus Redesign beginning on June 29, 2025, the Metroway was renamed into the A1X, discontinuing the Metroway branding. The route remained the same from the former Metroway counterpart. == Stations ==

There are 17 stations on the route. Twelve of the stations offer two-way service; three of the stations—18th & Crystal, 23rd & Crystal, and Fayette—are northbound-only; and two other stations—26th & Clark and 23rd & Clark—are southbound-only. The Metroway stations vary depending on location and jurisdiction, though all stations consist of side platforms and sidewalk-level bus stops. == See also ==
