It is located at the intersection of South Huntington Avenue and Heath Street on the border between the Mission Hill and Jamaica Plain neighborhoods.

Heath Street was the terminus of all weekday service (except nights) for three periods in 1977–1978 due to streetcar shortages and track work.

[4] Heath Street short turns were cut on February 11, 1983 when a snowstorm closed the line, and did not resume when it reopened.

[8] On October 13, 2012, the cut was quietly reversed by reducing frequency on the branch slightly, thus allowing the same equipment to cover the full line at no additional cost.

[12][13] The MBTA plans to modify the non-accessible surface stops between Heath Street and Brigham Circle with accessible platforms.

The new platforms are planned to be long enough to accommodate two 110-foot (34 m) Type 10 vehicles; Heath Street may also be modified to fit these longer trains.
