A $5.1 billion airport rebuild finishing in Salt Lake City, a $3.2 billion plan to double-track FrontRunner, a $2.9 billion I-15 reconstruction and a $1.2 billion new campus at Hill Air Force Base headline Utah'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 $16,210,829,000 (≈$16.2B) — and almost two-thirds of that total is three Wasatch Front programmes: The New SLC airport rebuild ($5.1B, counted once at its program total with its 2020–2024 phases disclosed, not split), FrontRunner 2X ($3,216,529,000, the FTA's published capital cost) and the I-15 Salt Lake City–Farmington reconstruction (≈$2.9B). Bases differ and are labelled on every record: program totals, published totals, one FTA capital cost, one final cost at opening and one committed-funding record (The Point, counted at its $165M public infrastructure figure only — the $2.3B beside it is private money and is not tallied). This is a majors list, not a census: UDOT alone announced $1.68B of new projects starting in 2025 and a $2.8B construction season in 2026, almost all of it below this page's $10M published-figure threshold or without a published project total of its own.
How the corridor and campus cases were handled: Hill AFB's East Campus is counted once at its published 10-year $1.2B program total; the $218,654,000 Mortenson depot-maintenance contract inside it is disclosed on the record, not listed separately. Bangerter Highway is counted once as its currently priced four-interchange package ($415.3M); the $700M-plus estimates for completing the corridor are not tallied. The West Davis Highway extension ($225M, 2026–2029) IS listed because it is a new, separately priced project — the original West Davis Highway is not (see exclusions). University of Utah hospital and medical-school builds are listed because their owner is the public university; their large philanthropic shares (Eccles gifts of $75M and $110M) are disclosed on the records rather than used to exclude them.
News- and trade-flagged sources: most UDOT figures on this page reach print through trade and local reporting of UDOT's own season announcements and briefings, flagged on their records — the I-15 widening (Davis Journal, UDOT briefing), Hill AFB (Davis Journal), the Eccles West Valley hospital (Construction Equipment Guide), Bangerter, Mountain View and 5600 South (ACP, UDOT figures), 1800 North (Construction Equipment Guide), Provo Airport (Citizen Portal, legislative presentation), West Davis extension and I-215 West (UDOT 2026 season reporting) and the North Capitol Building (DFCM figures at opening). The softest records are I-215 West (two UDOT season announcements price overlapping scopes at $190M and $150M; the later figure is counted and the earlier disclosed), 5600 South (UDOT's $361M project total against lower earlier contract figures, disclosed on the record) and the Spencer Fox Eccles School of Medicine (the university's $185M facility figure counted against $250M cited in campus reporting at opening, disclosed on the record).
Deliberately excluded: private and nonprofit builds are excluded however large — Intermountain Health (including its announced LDS Hospital replacement in downtown Salt Lake City, September 2026), Huntsman Cancer Institute, the Delta Center and the Smith Entertainment Group downtown sports district (a $900M arena-area share inside a $3B-plus private district, funded in part by a city sales-tax increment but privately owned), the Larry H. Miller Power District and its speculative ballpark, and private utilities (Rocky Mountain Power / PacifiCorp). Olympics: no 2034 Winter Games venue record is listed — the Games committee budgets just $31.2M of permanent capital investment across all venues (plus $206.2M of temporary infrastructure), no venue-by-venue funded project above this page's threshold with a published figure was verified, and the larger state venue figures in circulation ($96M spent, $140M-plus anticipated in commentary) are appropriations commentary, not priced projects. Unfunded / stalled: the Lake Powell Pipeline — no funded construction programme with a published current figure; named here, never listed as suspended. Utah Inland Port Authority project areas beyond the NWQ district publish subsidy and phased infrastructure estimates (e.g. about $50M + $50M for Spanish Fork) without a funded, priced project total, so no further UIPA record is listed. Completed in a prior year, however large: the original West Davis Highway (≈$910M total, opened January 2024), the Utah State Prison at its new Salt Lake City site (opened 2022 — its Draper land is now The Point, listed above for its new public infrastructure only), Provo Airport's 2022 terminal ($55M) and The New SLC's own earlier phases (inside the program total, not separate records). Three 2026 completions ARE listed under the current ruling — the North Capitol Building (opened January 2026), the Spencer Fox Eccles School of Medicine building (opened August 2026) and USU's Willis Veterinary Medical Education Building (opened June 2026) — while The New SLC, whose final gates open October 27, 2026, is carried as under-construction because that opening falls after this page's verification date.
