Interstate 290 (abbreviated I-290) is an auxiliary Interstate Highway in the U.S. state of Massachusetts, maintained by the Massachusetts Department of Transportation (MassDOT). Spanning approximately 20 miles (32 km) along a west–east axis, it is a spur route of I-90 (the Massachusetts Turnpike) in Central Massachusetts. In the west, it transitions into I-290 from I-395 at their shared interchange with the turnpike and Massachusetts Route 12 (Route 12) in Auburn. Among several state roads, it intersects with Route 146 (built as a direct connection to Millbury and Providence, Rhode Island) and I-190 in Worcester. Its interchange with I-495 and the Route 85 Connector in Marlborough serves as its eastern terminus.
I-290 begins as the continuation of I-395 in Auburn with exits to I-90, Route 12, and the Auburn Mall. 290 continues north through Worcester into Downtown, where Route 146 and I-190 split off. After 146, I-290 has exits for Route 122A, Route 122, downtown, and Route 9. After 190, 290 presumes east to a junction with Route 70, then continues over Quinsigamond Lake into Shrewsbury, where it goes northeast. 290 has a junction with Route 140 and starts east into Boylston and Northborough, where it travels northeast again. 290 enters Marlborough with an exit for Solomon Pond Mall and has its final junction with 495, where it terminates shortly after on the Route 85 Connector.
Originally, I-290 was to rejoin I-90 in Westborough, roughly where I-495 sits now. However, this route would have run through the town centers of Shrewsbury and Northborough. Additionally, I-290 was intended to be extended past I-495 to I-95/ Route 128 in Waltham, but this was canceled under pressure from towns along the planned route. A brief two-lane connector heads to Route 85 as a result of this aborted plan. The interchange with I-495 was originally supposed to be a cloverleaf, but after the plan was canceled, it was modified with a flyover ramp onto 495-northbound. The former exit 12 (Millbury Street eastbound and 146 south westbound) was closed when the Route 146 freeway was completed between the Mass Pike and I-290 in 2007.
Exit numbers on I-290 are a continuation of I-395 exit numbers. All interchanges were to be renumbered to milepost-based numbers under a project scheduled to start in 2016.  However, this project has now been indefinitely postponed.
