A $1.3 billion Amtrak bridge over the Connecticut River, a $925 million replacement for the 1896 WALK Bridge, a $721 million rebuild of the Gold Star Bridge's northbound span and a three-phase Meriden interchange headline Connecticut's public pipeline — a state rebuilding the Northeast Corridor it owns.
*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 ≈$5.3B ($5,323,207,552) — a rail-heavy tally for the state that owns the busiest commuter railroad in America: the top four records are all bridges or bridge programmes on the Northeast Corridor and the I-95/I-91 spine, and 11 of the 17 records are rail, rail-bridge or station work. Bases differ and are labelled on every record — three records are awarded construction contracts (Gold Star northbound, I-95 Exit 74, the SUBASE pier), two are federal design awards printed as design money only (Devon and Saugatuck replacements), and the rest are published total estimates or programme totals. This is a majors list, not a census of every CTDOT, campus and municipal job in Connecticut.
How the programme and paired cases were handled: the Meriden interchange is counted once at CTDOT's stated programme floor (more than $712M) with its three phases priced in the cost note; the Devon Bridge appears twice on purpose — a $110M construction project rehabilitating the standing 1905 bridge, and a separate $245.9M federal award designing its replacement — because CTDOT and the FRA fund and run them as two projects, and neither figure contains the other. The New Haven Line Power Improvement Program is counted once at its $122.8M federal award with its phases disclosed. At SUBASE New London only the one discrete, priced construction contract (the $87.8M pier replacement) is tallied; the Pier 8 design and Pier 31 extension beside it are disclosed on the record, not summed. The Gold Star corridor carries two records — the northbound rehabilitation and the separately numbered southbound shared-use path — as CTDOT itself separates them.
News-flagged sources: three rows rest on news or trade reporting of official figures, flagged on their records — the Connecticut River Bridge total (Railway Age, Amtrak figures), the Meriden programme total (New England Construction, CTDOT figures) and the Bradley expansion total (BusinessWest, Connecticut Airport Authority figures). Each record names the underlying official source. The softest records on the page are the UConn School of Nursing (a $50M capital-programme budget figure reported to the legislature, with no published completion date) and the Bulkeley Bridge rehabilitation (a capital-plan sheet total whose construction years are programmed but not yet scheduled). Completed EARLIER IN 2026, and listed under the current convention with the date printed on its record: Bradley International Airport's terminal expansion and inline baggage programme (≈$250M — baggage facility opened fall 2025, new concourse unveiled January 2026). The Windsor Locks station also opened in 2026 (October 18) but is listed as still building, because CTDOT states the full project — track and pedestrian-bridge works — completes in spring 2028.
Deliberately excluded: Yale University and Yale New Haven Health builds (private), Electric Boat's Groton facilities (a private company — only the federal SUBASE work beside it is listed), and private utilities' grid work. Prior-year completions, however large: the Route 8 / I-84 Mixmaster rehabilitation in Waterbury ($223M, completed October 2024 — its unfunded $3B-scale replacement concept is also excluded), the State Pier New London redevelopment (≈$255.5M–$311M, substantially completed February 2024; defect repairs since reported are unpriced and below the floor), the PeoplesBank Arena (former XL Center) renovation ($145M, city-owned, reopened October 2025), the Atlantic Street Bridge replacement in Stamford (2021), Bradley's Ground Transportation Center (2022), the SUBASE energy microgrid (completed in an earlier cycle) and the Gold Star southbound rehabilitation (2018–2020). Unfunded or study-stage: the I-84 Hartford viaduct replacement (alternatives under environmental review for a decade; the tunnel alternative alone was costed at $10–12B and ruled out; no construction funding or funded total exists — not listed even at design, and it is not the Bulkeley Bridge rehabilitation, which is a separate funded project and is listed), the Cos Cob (Mianus River) Bridge replacement (a $6.4M federal study grant against a $1.0B NEC estimate — below the floor as funded design), the Waterbury Mixmaster replacement, Hartford station relocation planning ($2.56M) and the proposed UConn Health hospital-acquisition bonding ($390M — an acquisition and partnership financing proposal, not a priced construction project). No discrete priced capital major over the floor was verified for the Connecticut State Colleges & Universities system this cycle — its capital programme runs as system-wide authorisations — and no Connecticut record is listed as suspended and no verified termination was found among the state's majors.
