Interstate 290 Massachusetts
Interstate 290 forms a loop connecting the city of Worcester south with the Mass Pike (Interstate 90) at Auburn and east to I-495, the outer beltway for Boston, at Hudson. The western end of I-290 shares a terminal point with Interstate 395 north from Connecticut. Interstate 190 stems north from I-290 at the eastern turn from Worcester to Shrewsbury and Northborough.
$6 million in construction at the east end of I-290 in Marlborough widens the entrance ramp from I-495 northbound to two lanes. Work runs through November 2023.2
A freeway loop north from I-90 (Massachusetts Turnpike) into Worcester was part of the original Interstate Highway System plans for the state of Massachusetts conveyed to the American Association of State Highway Officials (AASHO) on April 10, 1958. The Massachusetts Department of Public Works selected Route 90N for the loop because it lied north of I-90. This was revised to Interstate 290 by August 18, 1958 and included in the Interstate Urban Numerology for the state approved by AASHO on November 13, 1958.
Interstate 290 opened initially by Washington Square in September, 1960. Completion of the route occurred in 1970 with the extension to Marlborough.1
