Interstate 290 (I-290) is an auxiliary Interstate Highway in the US state of Massachusetts, maintained by the Massachusetts Department of Transportation (MassDOT). Spanning approximately 20 miles (32 km), it is signed as an east–west spur route of I-90 (Massachusetts Turnpike) in Central Massachusetts. The route begins in Auburn at I-90 as a northward continuation of I-395. It follows an L-shaped route, the nominally western half of which runs north into the city of Worcester, and, upon leaving the city, turns to the east to its eastern terminus at I-495 in Marlborough. Past I-495, the road continues as an unnumbered one-mile (1.6 km) connector to the town of Hudson.
