This exit list contains both the new exit number and former sequential exit number after MassDOT converted I-91 to the Geographic Reference or Milepost Exit Numbering system in March 2021. MassDOT started to convert exit numbers starting in October 2020, and though originally the project was to start with I-91, MA Route 140 was the first highway renumbered and I-91 the second in its exit renumbering contract. This project was first planned for 2016, but eventually postponed.

*Numbers in ( ) were those listed for the postponed 2016 renumbering project.
