This exit list contains both the current exit number and proposed future exit number when MassDOT converts I-90 to the Geographic Reference or Milepost Exit Numbering system. MassDOT plans to convert exit numbers between late summer 2020 and the spring of 2021 starting with routes in western and southern parts of the state. This project first planned for 2016, but eventually postponed. The future numbers provided were based on numbers provided on the MassDOT Exit Renumbering Project website route lists downloaded Nov. 21, 2019. * These were different numbers from the postponed 2016 project obtained from documents for:  Project 606619, downloaded on 10/7/15 (for Exits 1-10) and Project 606712 downloaded 4/12/16 (for Exits 11-18) and information from Project 606024, downloaded on 10/27/15, for Exits 20 to 26.

History behind the postponed projects to put up milepost exit numbers in 2016:

In May 2015 the MassDOT sign engineer responsible for the blanket contract indicated that the two projects to put up replacement signage along the Mass Pike may be using the existing sequential numbers due to the reconsideration of changing the state's exit numbers by top officials in the Highway Administration at MassDOT (see Interstate Exits Page). The contractors were told to prepare the exit tabs to be long enough to fit the milepost numbers, but may be told, when submitting their final spec drawings, to use the existing numbers. In October the same sign engineer indicated that for the foreseeable future, all sign replacement projects will use the existing exit numbers, but that the exit tabs and gore signs will be designed to display milepost based exit numbers, if/when the state adopts the system, this includes on the Mass Pike.(1) As of early January 2020, the western project is still listed as 36% (as it was in June 2017) but most of the new signs have been installed with the exception of the ramp sign westbound for I-291 and at least 1 advance sign westbound for Exit 1, most of the many new regulatory and auxiliary signs have been put up (see I-90 in Mass Photo Gallery). The eastern project is still listed at 13% as it was in 2017. Almost all the overhead signs are up, at least 1 sign support foundation needs to be created for a new advance sign for the I-95/128 exit in Weston. The contractor (Liddell Bros.) put up support posts for new ground-mounted signage in early 2019, but as of May has not placed any new signage onto it. New signage for the I-495 ramps was finally put up in early June 2019.  Exit list revised due to opening of two new ramps for I-95 and Route 30 at former Weston Toll Plaza westbound. The new exits are numbered 15B and 15A but the exit tabs have enough space to change this to a 3 digit number in the future (photos in the I-90 Gallery linked above).

I have a more detailed summary of the issues above in This Blog Post.
