Massachusetts Route 128
highway in Massachusetts

Route 128, known as the Yankee Division Highway, is an expressway in the U.S. state of Massachusetts maintained by the Highway Division of the Massachusetts Department of Transportation (MassDOT). Spanning 57 miles (92 km), it is the inner one of two beltways around Boston (the other being Interstate 495 [I-495]). The route's current southern terminus is at the junction of I-95 and I-93 in Canton, and it is concurrent with I-95 around Boston for 37.5 miles (60.4 km) before it leaves the interstate and continues on its own in a northeasterly direction towards Cape Ann. The northern terminus lies in Gloucester a few hundred feet from the Atlantic Ocean. All but the northernmost three miles (4.8 km) are a freeway, with the remainder being an expressway.
In local culture, Route 128 is generally recognized as the demarcation between the more urban inner suburbs and the less densely developed suburbs surrounding the city of Boston. It is furthermore used to reference the high-technology industry that developed from the 1960s to the 1980s in the suburban areas along the highway.
