split retired (Boston section)
Springfield and Boston.
MA 20A appears first in West Springfield in 1930 along Park Ave. By 1933, it extended up Carew St as it does now, including the section of road that is now US 20 from I-291 to Boston Road. This portion was given to US 20 when it was routed up I-291, sometime between 1972 and 1974.
The Boston area 20A first appears in my 1942 map as running down Market St from North Beacon to Beacon, then onto Beacon inbound. This route was removed in 1971.
