In the early 2000s, the MBTA modified key surface stops with raised platforms for accessibility as part of the Light Rail Accessibility Program. Portable lifts were installed at Heath Street and around 2000 as a temporary measure. For much of mid-2002, buses replaced weekend service to allow for the station construction. The accessible platforms at Northeastern, Museum of Fine Arts, Longwood, Brigham Circle, and Heath Street - part of a $32 million modification of thirteen B, C, and E branch stations - were completed in 2003.
