Mission Park station is a light rail stop on the MBTA Green Line E branch, located on Huntington Avenue in the Mission Hill neighborhood of Boston, Massachusetts. The station is located on a street running segment of the E branch; trains run in mixed traffic rather than a dedicated median. The station has no platforms; riders wait on the sidewalks (shared with bus stops for the route and buses) and cross the street to reach trains. Because of this, the station is not accessible. In 2021, the MBTA indicated plans to modify the Heath Street–Brigham Circle section of the E branch with accessible platforms to replace the existing non-accessible stopping locations. The new platforms are planned to be long enough to accommodate two 110 ft Type 10 vehicles. Design work began in July 2023 and is expected to reach 15% completion in July 2024.
