This exit list contains both the current exit number and proposed future exit number when MassDOT converts I-495 to the Geographic Reference or Milepost Exit Numbering system. MassDOT plans to convert existing exit numbers starting in late summer 2020 with routes in the western and southern parts of the state. This project was first planned for 2016, but eventually postponed. The future numbers listed are those provided at the MassDOT Exit Renumbering Project website, downloaded Nov. 21, 2019.

*Numbers in ( ) listed for the postponed 2016 Renumbering Project.

Here's a sign plan for the current I-495 Sign Replacement Project for the northernmost section between Methuen and Andover:

Image of MassDOT sign plan showing new I-495 Exits 48 and 49 sign plans  with exit tabs with room for larger milepost based numbers

The plans show wider exit tabs for future placement of milepost based exit numbers. The Exit 49 tab is wider since the proposed exit number is 107A. More sign plan photos in I-495 in Mass. Gallery.
