South Street station serves as a surface-level light rail stop on the MBTA Green Line's B branch. It is situated within the median of Commonwealth Avenue, just east of South Street in Boston's Brighton neighborhood, Massachusetts. Among all B branch stops, it records the fewest boardings, with approximately 214 daily riders reported in 2011.
Planned closure
During the 2018–19 track maintenance, which involved replacing platform edges at multiple stations, new mandates for accessibility enhancements were triggered. By December 2022, design progress for South Street and four additional B Branch stations reached 30% completion. A design proposal released in March 2024 recommended merging the Chestnut Hill Avenue and South Street stops into a single accessible station positioned between Chestnut Hill Driveway and Chestnut Hill Avenue.
In May 2024, the Federal Transit Administration granted $67 million to the MBTA to fund the construction of accessible platforms at 14 stops across the B and C branches, including the proposed consolidated station. Further stations were incorporated into the B branch accessibility project later in 2024. As of February 2025, the MBTA intends to issue a request for bids on a $74 million design-build contract by May 2025. Construction activities are slated to begin in fall 2025 and continue through mid-2027.
