| Introduction | XVII | Added a new Table of Contents to the PDF version of the document. |
| Chapter 1 | 1-5, 1-6, 1-7 | Included a new section following Figure 1-2 (Boston Region MPO Membership) that lists the names of MPO members and designees by MPO Board seat. |
| Chapter 3 | Page 3-6 | Corrected two mentions of Table 3-7 that instead correspond to Table 3-8, the FFYs 2027–31 TIP Highway Table |
| Chapter 3 | Page 3-6 | Added two bullet points preceding "Projects funded with earmarks or discretionary grant funds" and "State-prioritized bridge repairs..." |
| Chapter 3 | Table 3-8 | Included a new "FFYs 2027–31 TIP Highway Table" to reflect updates to the MassDOT Statewide Highway Program. The program now lists funding for Project 610680- Natick- Lake Cochituate Path in FFY 2027. |
| Chapter 3 | Table 3-9 | Updated the table header to note "FFYs 2027–31" in the seventh and eighth columns rather than "FFY27–31". |
| Chapter 3 | Table 3-9 | Updated the footnotes in the table to omit mention of the Green Line Core Capacity funding, as this footnote was incorrectly retained from the FFYs 2026–30 TIP. Core Capacity funding was solely included in FFY 2026 of that TIP, and is therefore not included in this TIP. |
| Chapter 3 | Table 3-10 | Fully spelled out "FFY 2026" and "FFYs 2027–31" in the fifth and sixth columns of the table, rather than "FFY26" and "FFY27–31". |
| Chapter 3 | Table 3-10 | Updated the footnotes in the table to omit mention of the Green Line Core Capacity funding, as this footnote was incorrectly retained from the FFYs 2026–30 TIP. Core Capacity funding was solely included in FFY 2026 of that TIP, and is therefore not included in this TIP. |
| Chapter 3 | Table 3-10 | Corrected a header under the RRIF/TIFIA Financing Program section that incorrectly read "Projects Potentially Funded by Federal" to "Projects Potentially Funded by Federal Dollars". |
| Chapter 3 | Table 3-11 | Updated the MWRTA TIP Transit Table to include a new "Other Information" column. The funding figure for Project #RTD0011137 "MetroWest RTA- Acquire Revenue Replacement Vehicles Cutaways Type D CNG" has also been updated to reduce the $600,000 previously listed for state RTACAP funds down to $156,114. This project also now includes $208,777 in matching Toll Credits. |
| Chapter 3 | Table 3-12 | Updated the CATA TIP Transit Table to include a new "Other Information" column. |
| Chapter 4 | Minor grammar and formatting fixes made throughout the chapter. | |
| Chapter 4 | Page 4-2 | Removed sentence referencing MPOs goal and objectives due to redundancy following document restructuring. |
| Chapter 4 | Page 4-7 | Changed a reference to Chapter 6 to be for Chapter 5 following renumbering of chapters. |
| Chapter 4 | Page 4-62, 4-65, 4-66,4-69 | Removed all references to updating CMAQ (PM3) Targets in FFY 2027 as timelines are currently unclear. MPO and MassDOT staff are currently seeking clarification on the necessary timelines to set CMAQ from FTA. |
| Chapter 4 | Page 4-33 | Added footnote that references the Transit Agencies Public Transit Agency Safety Plans (PTASP) |
| Chapter 4 | Page 4-52 | Added footnote that references the Transit Asset Management (TAM) Plans |
| Chapter 4 | Page 4-6 | Corrected a typo that referenced the safety event rate instead of safety events. |
| Chapter 4 | Page 4-7 | Indicated that CATA is allowing for some regression in both demand response and fixed-route demand performance; previous version indicated that regression was only happening for demand-response. |
| Chapter 4 | Table 4-21 | Titles in table should reference a single calendar year instead of a range of years. |
| Chapter 4 | Figure 4-1 to 4-5 | Updated figures such that 2021–25 Statewide values are visualized as "MA Projected Forecasts". |
| Appendix A | Table A-5, A-6, A-7, A-8 | Corrected two abbreviations in Table A-5, A-6, A-7, and A-8 that listed two bonus criteria as relating to the "CAHQ" MPO goal area rather than "CAHC", standing for "Clean Air and Healthy Communities". |
| Appendix B | Table B-1 | Updated the table to clarify GHG Analysis Types for several projects that previously did not list a type. Each unlisted project should have been categorized as "Not Applicable". |
| Appendix B | Table B-2 | Updated the table to clarify GHG Analysis Types for several projects that previously did not list a type. Each unlisted project should have been categorized as "Not Applicable". |
| Appendix C | Table C-2 | Included Table C-2, which lists the public comments submitted for consideration during the public comment period for the Draft FFYs 2027–31 TIP. |
| Appendix E | E-3 | Omitted mention of the "National Goals" under the Infrastructure Investment and Jobs Act. These are redundant to the subsequent "Federal Transportation Planning Factors" section, and this change is consistent with the listing of Federal Transportation Planning Factors in other Massachusetts MPO TIPs. |
| Appendix G | G-2 through G-27 | Included tables G-1,G-2, G-3, and G-4. These tables summarize operating and maintenance expenditures that were incurred or are projected by MassDOT, the MBTA, the Cape Ann Transportation Authority, and the MetroWest Regional Transit Authority.
