Editing Interstate 91 (section)

== Exit list ==
All interchanges in Massachusetts were to be renumbered to [[Milepost-based exit numbering|milepost-based numbers]] under a project scheduled to start in 2016. However, this project was indefinitely postponed until November 18, 2019, when the [[Massachusetts Department of Transportation]] (MassDOT) confirmed that, beginning in the middle of 2020, the exit renumbering project will begin.<ref name="Exit Numbers">{{cite web |author = Commonwealth of Massachusetts |year = 2015 |work = COMMBUYS |title = Bid Solicitation FAP# HSIP-002S(874) Exit Signage Conversion to Milepost-Based Numbering System along Various Interstates, Routes and the Lowell Connector |url = https://www.commbuys.com/bso/external/bidDetail.sdo?docId=BD-16-1030-0H100-0H002-00000005477&external=true&parentUrl=bid |access-date = January 5, 2016 |archive-date = September 25, 2015 |archive-url = https://web.archive.org/web/20150925092338/https://www.commbuys.com/bso/external/bidDetail.sdo?docId=BD-16-1030-0H100-0H002-00000005477&external=true&parentUrl=bid |url-status = live }}</ref><ref name="ma" /> On March 1, 2021, MassDOT confirmed that the exit renumbering on I-91 will start on March 3, and it will last for two weeks.
