It is an alternate route of Massachusetts Route 122, with a mile-long concurrency with its parent route in downtown Worcester.Route 122A begins in the Farnumsville section of Grafton at its parent route. Route 122A heads westward, crossing the Blackstone River and following it through the northwest corner of Sutton and into Millbury. In Millbury, Route 146 crosses the river again, passing through the center of town before meeting Route 146, near the Shoppes at Blackstone Valley shopping center. The two routes travel northward, with a combined exit to U.S. Route 20 and the Massachusetts Turnpike (I-90) shortly after the merge, and just before the two routes enter Worcester.
