Boston

In 1939, C37 came up Gallivan Blvd (as a reverse multiplex with MA 3) to Old Colony Parkway, then up Columbia Rd to Dorchester Ave. The map is unclear where it goes (if anywhere) after Summer St. The 1942 map shows it up Congress St. C37 was replaced by MA 3A between 1959 and 1966 along Gallivan Blvd; the rest was simply decommissioned.
