Route 146 is a 20.99-mile (33.78 km) north-south expressway 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 the expressway 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.
