MassDOT to continue exit renumbering work on I-495

Massachusetts

BOSTON (WWLP) – MassDOT will be working to complete the new milepost-based signs at all exits along Interstate 495, between Middleborough and Amesbury, by Saturday, June 12, 2021.

By the end of the week, MassDOT will have completed converting the exit numbers on the following corridors to a milepost-based numbering system, per Federal Highway Administration (FHWA) requirements: 

  • Interstate 84
  • Interstate 90
  • Interstate 91
  • Interstate 93
  • Interstate 95
  • Interstate 190
  • Interstate 195
  • Interstate 295
  • Interstate 495
  • Route 2
  • Route 3
  • Route 6
  • Route 24
  • Route 25
  • Route 128
  • Route 140
  • Route 146
  • US Route 3

The remaining two corridors, Interstate 290 and Interstate 395, will be converted to milepost-based exit numbering in August 2021. Note that the overhead guide signs and sign structures currently being installed on I-290 are a part of a separate MassDOT project. As this project was designed and begun well before the start of the Statewide Exit Renumbering Project, these signs have been fabricated with the current sequential exit numbers. Once the sign replacement work is complete, all of the exit numbers will then be overlaid with the new milepost-based numbers.  

Previous to this project, interstates and major roadways in Massachusetts have always utilized a sequential exit numbering method.

All work is weather dependent and construction dates may be adjusted as conditions warrant.
