The Massachusetts Department of Transportation (MassDOT) is in the process of converting all exit numbers on freeways to a milepost-based numbering system, per Federal Highway Administration (FHWA) requirements. Currently, interstates and freeways in Massachusetts utilize a sequential exit numbering method. Construction began in the Fall of 2020 and is anticipated to be completed in the Summer of 2021.

Exit numbering conversion will begin on the MassPike/Interstate 90 on December 13, 2020. Construction details are as follows:

• Corridor: Interstate 90 (Massachusetts Turnpike)
• Location: Boston to West Stockbridge
• Approximate start date: Dec. 13
• Approximate construction duration: 4 weeks
• Hours of operation: 8:00 PM – 5:00 AM

Please note that all work is weather dependent and construction dates may be adjusted accordingly. This work will not impact the tolls on this roadway.
