This exit list contains both the current exit number and proposed exit number if/when MassDOT converts I-93 to the Geographic Reference or Milepost Exit Numbering system. MassDOT awarded a contract to replace the exit numbers in December 2015 and was supposed to be switching over routes in western and southern parts of the state in 2016, however the project now has been indefinitely postponed. The proposed numbers provided were based on contract documents provided by the MassDOT Highway Division for the postponed project, and may be subject to change.

*Recommended Changes: MassDOT was to review the proposed exit numbers for possible changes prior to work to create the new exit tabs. If the project ever goes forward, here's some changes I'd suggest:

Exit 18C Northbound-There is no ramp to MA 1A Northbound, proposed Exits 18 A/B SB, there should then not be a suffix on the northbound exit, which should just be 18.

+ Exit numbers in the O'Neill (Big Dig) Tunnel are to be switched under a separate contract that was awarded to Liddell Bros. of Halifax in March 2016. This project is not planned to occur until the time the main project is changing numbers on the rest on I-93.

** New left bannered exit tabs were added to existing Left-side Overhead signs at I-95 South exit in December 2013, the I-95 South Providence Exit number was changed from Exit 1 to Exit 1A and the thru lanes for I-95 North received a Exit 1B designation.

***New exit opened on October 18, 2017 as part of Methuen Rotary replacement project. (See http://blog.mass.gov/transportation/massdot-highway/methuen-rotary-project-i-93-new-exit-46b-now-open/)
