NY line in Egremont to Woronoco via Great Barrington.
Upgrades and Multiplexes
Cosigned with US 7 through Great Barrington.
Brief multiplex with MA 8 in Otis.
See the entry for MA 17 for details on the route numbering; Rt 23 first appears on my 1939 map from the NY line to Woronoco. The route is still the same now.
