A $2.14 billion Sagamore Bridge finally in procurement, a $1.2 billion drawbridge rising at North Station, the two most expensive public schools in state history, and a replacement veterans home in Holyoke headline Massachusetts' public pipeline.
*How to read the total: the sum of the published figures in the list below. Bases differ by project — most are total cost estimates, some are federal grants, program totals, or construction contracts as awarded. Each project's expanded view labels its own basis. We add them up with the labels showing rather than pretend they're all the same kind of number.
Hover a pin for the project snapshot. Pin numbers match the project list below. Locations are approximate (nearest city or corridor midpoint) on a schematic state outline.

17 major public projects are listed. The listed figures sum to ≈$8.7B ($8,655,852,988) — a smaller tally than Massachusetts' reputation suggests, and the coverage note explains why: the state's biggest builders by dollars (Harvard, MIT, Mass General Brigham, Boston Children's, Dana-Farber, BU, Northeastern, Tufts) are all private and are excluded by the owner rule, however large their projects. Bases differ and are labelled on every record — construction estimates, an awarded design-build contract, authorised budgets and, for three MassDOT lines, amounts programmed in the FY2026–30 Capital Investment Plan. This is a majors list, not a census of every city and town job in Massachusetts.
How programme and phasing cases were handled: the Cape Cod Bridges Program is counted ONCE, at its funded Sagamore phase ($2.14B construction estimate; about $2.42B all-in funded) — the Bourne Bridge phase ($2.4B estimate) is unfunded and is not tallied. West-East Rail is counted once at the funded Worcester–Springfield Inland Route phase (≈$135M); the $36.8M Springfield design award and the $130M Springfield Hub Modernization grant announced October 16, 2026 are phases of the same Springfield work and are disclosed on the record, not added. Massport's $4.1B capital plan and the MBTA's $9.8B FY26–30 capital plan are programme contexts disclosed on their discrete records, never tallied as projects. The Kernwood/Hall-Whitaker pair is listed once at the CIP's single combined line.
News-flagged sources: most Massachusetts majors in this cycle rest on news or trade reporting of official figures, flagged on their records — the Sagamore estimate (Cape Cod Times, MassDOT DEIS), Draw One (Railway Track & Structures, MBTA figures), the Logan TERC value (Bisnow / Boston Business Journal, Massport figures), Lexington (Lexington Observer, MSBA vote), Revere (Boston Herald survey of MSBA approvals), Holyoke (ENR, state figures), Quincy (Streetsblog, MBTA CIP), Salem (ENR) and the Inland Route total (The CoolDown, FRA/MassDOT figures). The softest records on the page are I-90 Allston (a $424M programmed design/programme figure against a ≈$1.9B unfunded build, with $327M of its federal grant rescinded in July 2025 — all printed on the record), Revere High School (an approval-stage figure with no verified construction start) and the two CIP-line records (I-195/Route 18 and Kernwood/Hall-Whitaker), whose figures are programmed money, not contracts.
Deliberately excluded: PRIVATE INSTITUTIONS, named because they dominate Boston construction: Harvard University, MIT, Boston University, Northeastern University and Tufts University expansions, and the Mass General Brigham, Boston Children's Hospital and Dana-Farber Cancer Institute building programmes — all private, excluded however large. UMass Memorial Health is a private nonprofit and is likewise excluded (UMass Chan Medical School, the public school, is treated separately below). Also excluded: South Station Expansion and the Red–Blue Connector (no funded construction; design/planning only in the sources reviewed); the Bourne Bridge phase of the Cape Cod Bridges Program (federal funding pending — named on the Sagamore record); South Coast Rail Phase 2 / Phase 1 extensions beyond the opened line (unfunded); private offshore wind farms (Vineyard Wind, SouthCoast Wind — the publicly owned terminals that serve them ARE listed); and Boston's White Stadium redevelopment (a municipal–private partnership whose public/private cost split was in litigation and flux in the sources reviewed — no clean public figure verified). Completed in a prior year, however large: South Coast Rail Phase 1 (opened March 2025), the Green Line Extension (2022), Logan Terminal E's 320,000 sq ft expansion (opened October 2023), UMass Chan's $350M New Education & Research Building in Worcester (opened June 2024), UMass Amherst's $125M Manning CICS building (slated spring 2025), the Chelsea Veterans Home replacement (opened 2023–24) and the Tobin Bridge / Chelsea Curves programme. Completed EARLIER IN 2026 and LISTED under the current ruling: the UMass Amherst School of Public Health & Health Sciences Hub ($43M, opened May 1, 2026) — the only verified 2026 completion among Massachusetts majors in this cycle; the Quincy Bus Facility (expected December 15, 2026) and the Holyoke Veterans Home (occupancy late 2026) were still building at the October 26, 2026 build date and are listed as under construction with their dates printed. No verified termination was found among Massachusetts majors in this cycle — the Allston grant rescission is a funding termination for one grant, disclosed on a record that remains listed at design on surviving programmed money, not a terminated project.
