MA 10 is a north/south route through the Pioneer Valley region of Massachusetts. CT 10 becomes MA 10 upon entering the state multiplexed with US 202. The two routes run north through Westfield and have an interchange with the Massachusetts Turnpike (I-90) at exit 41. Shortly thereafter, US 202 splits off to the east toward Holyoke, while MA 10 continues to the north. In Northampton, it joins US 5, and the two routes are multiplexed for much of the remainder of their length in the state. In Bernardston, MA 10 splits off to the east. After crossing the Connecticut River, it turns north onto MA 63. The two routes are multiplexed until just south of the state line, where they split. MA 10 continues north into New Hampshire as NH 10.
