The Anacostia Initial Line Segment is a 1.1-mile planned streetcar line connecting the Anacostia Metro Station with the Joint Base Anacostia-Bolling (JBAB), via Firth Sterling Avenue and South Capitol Street. The line includes a storage yard and maintenance facility adjacent to South Capitol Street.
A part of the second phase of this project would extend the line through historic Anacostia, running between the Anacostia Metrorail Station and the 11th Street Bridge. The alignment for this "Anacostia Extension" has not yet been chosen. It is still under study and is not funded for construction.
