A plutonium pit factory counted at the top of a $2.7–3.9 billion range, a $2.2 billion water pipeline to the Navajo Nation, a $1.4 billion pipeline off the Ogallala, WIPP's $770 million ventilation rebuild and the largest road programme in NMDOT history headline New Mexico'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.

17 major public projects are listed. The listed figures sum to $10,690,426,324 (≈$10.69B) — and the total needs its health warning printed with it: two records dominate and both are ranges, not prices. LAP4 is counted at the $3.9B high end of NNSA's 2021 CD-1 range ($2.7–3.9B, no baseline yet), and the Navajo-Gallup system at Reclamation's current $2.2B estimate against a lower congressional ceiling. Bases are labelled on every record — programme totals for the three big water systems, published project totals, and one approval document. This is a majors list, not a census: NMDOT alone reported 71 active construction projects worth ≈$1.48B in mid-2026, most below this page's published-figure floor, and the state's June 2026 sale of the first $220M of a $1.5B transportation bonding programme will price more of them.
Tribal-government projects — listed under the owner's October 26, 2026 scope ruling: tribal governments are sovereign owners, and under the October 26, 2026 ruling they are in-scope where the tribe is the documented project owner or federal grant recipient, so their majors are now listed, not just named. Taos Pueblo (Abeyta) Settlement implementation (nm-016): a $144M total settlement under the Claims Resolution Act of 2010 — $88M of federal funds to the Pueblo Water Development Fund and $48M for mutual-benefit projects (wells, mitigation and water treatment work with the Town of Taos), implementation continuing since the settlement took effect in 2016. LeChee Water System Improvement Project (nm-017, Navajo Nation): a $43M Navajo Nation project launched May 2025 at LeChee Chapter — a membrane treatment plant, pump stations, storage and about 31,000 feet of pipeline repurposing the former Navajo Generating Station's Lake Powell intake (the chapter sits on the Arizona side of the Nation; the project is carried on this page because the owner is the Navajo Nation). The distinction that now labels this page's water records: where the constructing owner is federal — the Bureau of Reclamation's Navajo-Gallup and Pojoaque Basin systems — the project is listed as a federal record even though it serves tribal communities; where the owner is the tribal government itself, it is listed as a tribal record under the same ruling.
Deliberately excluded — private builds, however large: Pattern Energy's SunZia Wind and Transmission project — a 3,650 MW wind farm in Lincoln, Torrance and San Miguel counties and a 550-mile HVDC line to Arizona, ≈$11B, which entered commercial operation in June 2026 — is the largest energy build in state history and is excluded solely because its owner is private; the same rule excludes Intel's Rio Rancho expansion, Meta's Los Lunas data centres, other data-centre and mining builds, and PNM's proposed ≈1.7 GW resource portfolio (800 MW wind, 240 MW solar, 610 MW storage, 40 MW gas, filed June 2026), which is a private utility procurement, however public its regulation. Completed in a prior year, however large: UNM Hospital's Critical Care Tower ($842M — the largest public non-road construction project in state history — opened October 5, 2025, and is therefore a 2025 completion, excluded under the ruling and named here with its figure and date); the Albuquerque Sunport's 'Dream of Flight' terminal renovation (≈$90M, completed spring 2025); Albuquerque Rapid Transit (ART, opened 2019); and Spaceport America's original build ($218.5M, first phase complete FY2016 — the Spaceport Authority reports ≈$32–39M of smaller capital projects under way, but no single current project over $10M with a published price could be verified, so none is listed). Priced but not listed, for scope or stage: NMSU's Thomas & Brown engineering building replacement (demolished 2025; $22.5M GO bond plus $10M General Fund identified, but no published total project cost — a figure is required to list) and its $18.8M O'Donnell Hall expansion; NMDOT's I-25 Gibson Boulevard interchange (≈$150M, design-build letting expected late 2028) and NM 128 reconstruction (≈$100M, Lea County) — both published in the department's major-projects table and expected to qualify at the next update once their records firm up; and Kirtland Air Force Base, for which no current priced MILCON project over $10M could be verified (the Sandia projects on the base's federal enclave are listed under their own owner). No 2026 completion is listed: UNM's CCAT carries an October 2026 completion date but no published opening at verification, and WIPP's ventilation system is in commissioning — both are carried as under-construction rather than claimed as completions.
The softest records, flagged where they stand: LAP4 (a 2021 range with no baseline, against GAO's finding that the wider programme has no credible integrated estimate), the EPCU transmission line (a $215–349M budget-document range at pre-construction, with a ≈$368M watchdog figure disclosed on the record), and the Border Highway Connector (an estimate that already doubled from $80M, rescued by the 2026 bond sale). New Mexico's federal science estate — two national laboratories, WIPP and two Reclamation water systems — is about $8.0B of this page's $10.5B total; the state's own road, bridge and university building is the rest.
