The below press release was submitted to us by the MassDOT.

The Massachusetts Department of Transportation (MassDOT) has completed converting all exit numbers on freeways to a milepost-based numbering system, per Federal Highway Administration (FHWA) requirements. Freeways in Massachusetts previously utilized a sequential exit numbering method. The following corridors now have milepost-based exits: 

• Interstate 84
• Interstate 90
• Interstate 91
• Interstate 93
• Interstate 95
• Interstate 190
• Interstate 195
• Interstate 290
• Interstate 295
• Interstate 395
• Interstate 495
• Route 2
• Route 3
• Route 6
• Route 24
• Route 25
• Route 128
• Route 140
• Route 146
• US Route 3

Please note that “Old Exit” signs have been installed at the one-mile advance sign and gore signs. These signs will be up for a minimum of two years to help with the transition. The project team has provided mapping services with information on the new exit numbers for all of the corridors. The timing of the exit number updates may vary by platform as they will be completed on their own individual schedules. For a full list of corridors, and their old and new exit numbers, please visit the project website at newmassexits.com.

For more information on the project, or to submit a comment or question, please visit the project’s website. If needed, a GIS shapefile with the specific numbering information is available on Massachusetts’ GeoDOT site.
