Route 146 is a 20.99-mile (33.78 km) north-south state highway in the U.S. state of Massachusetts, maintained by the Massachusetts Department of Transportation (MassDOT). Spanning approximately 21 miles (34 km) along a south–north axis, it is a continuation of Route 146 in Rhode Island, which splits from I-95 in Providence. The southern terminus within Massachusetts exists in Millville, where it enters the state from North Smithfield, Rhode Island. Among several local roads, Route 146 intersects with the Massachusetts Turnpike (I-90) in Millbury and I-290 in Worcester before arriving at its northern terminus at the intersection of several surface streets in downtown Worcester. Most of the route is a freeway, except for a short section near the boundary between Millbury and Sutton where there is driveway access and at-grade crossings.
