CT line in Agawam to Springfield
Appears in my 1930 ALA Green book. In there, it shows 5A crossing the river on the South End Bridge at Meadow St. The 1942 map routed it up Main St in W. Springfield to River and then to Park. From Park, it went up Elm to end at US 5. This map also shows it as MA 5A. Robert Droz gives the date for this changeover as 1938. South of the state line remained 5A. 5A was changed to 159 between 1967 and 1969 on maps.
