A $2.84 billion dry dock rising at Pearl Harbor, the $1.66 billion final segment of Honolulu's Skyline, a capped $350 million state stake in a new Aloha Stadium, a $298 million plan to move West Maui's highway inland and a storm-closed hospital on Maui headline Hawaiʻi's 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.

12 major public projects are listed. The listed figures sum to $6,151,600,250 (≈$6.15B) — and two records dominate it: the Navy's $2.84B Dry Dock 5 contract at Pearl Harbor and HART's $1.66B Skyline Segment 3 contract. Bases differ and are labelled on every record: firm contracts, published project totals, a capped state contribution, planning-level estimates and one federal grant. This is a majors list, not a census: HDOT's highways, airports and harbors programs, the state capital budget and the services' Hawaiʻi MILCON lists carry many smaller projects below this page's $10M published-figure threshold. No 2026 completion is listed: Hawaiʻi's big recent openings all landed in 2025 or earlier (below), and the one candidate 2026 finish — the $14M Lahaina wastewater R-1 improvements — could not be date-verified, so it is named on its neighbour record rather than printed as a completion.
Completed in a prior year, however large: Skyline Segment 1, East Kapolei to Aloha Stadium (opened June 30, 2023) and Skyline Segment 2, the Airport segment to Middle Street (opened October 16, 2025) — the operating railway Segment 3 now extends; the Kapālama Container Terminal at Honolulu Harbor (final cost about $555M; Phase 1 opened 2020 and Phase 2's roughly 1,800 feet of new berthing was completed in 2025); HNL's Mauka Concourse ($220M, opened 2021); the Hawaiʻi State Hospital's new patient facility ($160M, 144 beds, completed 2021 in Kāneʻohe); and UH Mānoa's Hale Haukani student housing ($170M, opened August 18, 2025 — also excluded on ownership: it is privately owned and financed by the Collegiate Housing Foundation and operated by a Greystar subsidiary on leased university land, a developer-owned P3, as is UH's earlier $70M RISE residence). Red Hill — excluded as environmental remediation, per this series' treatment of cleanups, however large: the Red Hill Bulk Fuel Storage Facility was defueled (over 104 million gallons, completed March 2024) and is being permanently closed after the 2021 fuel release contaminated a drinking-water aquifer; Congress secured about $2.2B for remediation, closure and health response, the Navy's closure-in-place proposal was priced at about $120M, and the permanent Red Hill Water Treatment Facility (P-716) was contracted on August 11, 2026 at $309,650,002 for completion in August 2029 — all of it closure and remediation program, named here at full scale rather than listed as construction.
Deliberately excluded — private builds and unpriced planning: the Thirty Meter Telescope on Mauna Kea (an international university consortium's project, estimated about $3B; construction halted since the 2019 protests, the National Science Foundation dropped it from its Extremely Large Telescope funding track in 2025, and in September 2026 the consortium declined Spain's €1B La Palma offer and recommitted to Mauna Kea with a roughly $1B funding gap — named carefully at its published status: stalled, unfunded to completion, and not a public build); Hawaiian Telcom's $1.7B private fiber build; hotel, resort and condominium construction statewide; and the Pasha Group's private share of the Kapālama terminal works. Unfunded or unpriced planning, named not listed: HNL's Diamond Head Concourse replacement — announced in 2018 at $1.1B and described by HDOT's director in October 2026 at $2.1B, a disagreement printed here rather than resolved by picking one; the Pearl Harbor Waterfront Production Facility (planning and design funded at $105M, construction unpriced); the Hawaiʻi State Hospital defect-remediation bonds proposed at $28.84M in a 2025 bill that did not pass; and most Maui wildfire recovery spending, which is housing assistance and private rebuilding rather than priced public construction — the two verifiable public infrastructure records (Waikapū wastewater and Lahaina recycled water) are listed. Native Hawaiian agencies, for the record: Hawaiʻi has no tribal governments in the mainland sense; the Office of Hawaiian Affairs and the Department of Hawaiian Home Lands are state agencies, so their buildings would be listed as state projects if priced above the floor — no individually priced OHA or DHHL building project above $10M could be verified for this page (DHHL's roughly $40M-a-year infrastructure repair line is a budget program, not a project), and Native Hawaiian-serving nonprofits are private owners under the rule and excluded on that basis.
One judgement call runs through the defense records and is disclosed on each: Hawaiʻi's MILCON pipeline is funded in increments, so authorized project totals (Wheeler, $231M; Kāneʻohe Bay, $203.5M) are printed as published project figures with their appropriations-stage status flagged, while the one firm construction contract (Dry Dock 5) is counted at its contract value. Increments of those same projects appearing in later defense bills — such as the $492.7M Dry Dock increment in the FY2026 NDAA — are inside the figures listed, never added to them.
