This exit list contains both the current exit number and proposed exit number if/when MassDOT converts I-90 to the Geographic Reference or Milepost Exit Numbering System. MassDOT let two separate contracts to upgrade highway signage along the Mass Pike. The first was awarded on August 18, 2015 (Project 606619) for signage from Exit 1 at the state line to Exit 10 in Auburn. The second contract (Project 606712) to replace signs between Exits 10A and 18 was advertised on November 28, 2015 and the winning bid was announced on February 2, 2016. This project received its Notice to Proceed in May 10, 2016, and is due to be completed by the spring of 2018. These contracts were to install signs with new exit numbers based on I-90 mileposts. MassDOT also planned to update the numbers from Exits 20 to 26 under a blanket contract (Project 606024) to revise the exit numbers on all other interstates and state highways, the winning bid for this contract was announced on November 17, 2015. The projects will now install signs with the existing exit numbers, but designed to hold the new numbers some time in the future. Original project documents available online from MassDOT provided the proposed numbers for this segment of the Mass Pike. The Proposed Exit Numbers listed are from MassDOT contract documents for Project 606619, downloaded on 10/7/15 (for Exits 1-10) and Project 606712 (downloaded 4/12/16) and information from Project 606024, downloaded on 10/27/15, for Exits 20 to 26.

*UPDATE (8/6/17): 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 have been 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 August 2017, the western project is still listed as 36% (as it was in June) complete with many sign support foundations having been created, support posts installed and with at least 11 new signs placed (6 for Exit 10 EB + WB, 4 for Exit 8 EB + WB and 1 EB for Exit 9), also 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 June. At least 1 sign support foundation has been created and many more sign placement tags have been placed along the highway by the contractor. It appears the contractor (Liddell Bros.) has been working on the new signage in relation to the Toll Plaza Demolition Project, mostly completed in November 2017, than the Sign Replacement contract. 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.
