ExitRenumbering_InProgress_TwitterBOSTON – The Massachusetts Department of Transportation (MassDOT) is announcing that it will begin installing new milepost-based signs for all exits on Interstate 91, from the Vermont border to the Connecticut border, tomorrow, Wednesday, March 3.  The milepost sign installation operations will take place during overnight hours from 8:00 p.m. to 5:00 a.m. the following day. The work is anticipated to be completed in two weeks.

Sign installation work continues on Interstate 95 this week. The work, which began on Thursday, February 25, is scheduled to continue for approximately 10 weeks.  This corridor has been broken up into four construction segments as follows:

  • Interstate 95 between the New Hampshire border and Route 128
  • Interstate 95 between the Route 1 interchange and Route 20
  • Interstate 95 between the Interstate 90 interchange and Westwood and Canton
  • Interstate 95 between Neponset Street and the Rhode Island border

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

The MassDOT Statewide Exit Renumbering Project is converting all exit numbers to milepost-based signs on roadways, per Federal Highway Administration (FHWA) requirements. Previous to this project, interstates and major roadways in Massachusetts have always utilized a sequential exit numbering method.

For information on the scheduled installations, please visit: https://newmassexits.com/#it-schedule. If needed, a GIS shapefile with the specific numbering information is available on Massachusetts’ GeoDOT site.
