A $2.8 billion rebuild of I-70 across the whole state, a new 1,200-foot lock on the Mississippi at Winfield, two bi-state river bridges at St. Louis and Chester, a $471 million I-44 rebuild in the southwest, and a new research reactor rising at Mizzou headline Missouri'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.

16 major public projects: 5 in the Kansas City area, 3 in mid-Missouri (Columbia and Jefferson City), 2 in St. Louis, 2 in Springfield and the southwest, 2 Mississippi River crossings listed as bi-state, plus Fort Leonard Wood and Whiteman AFB. The listed figures sum to ≈$6.92B. Two records are BI-STATE totals, listed once and labeled as such: the I-270 Chain of Rocks Bridge contract (≈$496.2M, shared 50/50 by Illinois and Missouri) and the Don Welge Memorial Bridge at Chester ($307.1M final cost, with Illinois investing ≈$143.2M) — neither figure has been halved or doubled in the tally, and neither should be read as Missouri-only spending. Lock & Dam 25 straddles the state line at the river; it is listed here because the new lock chamber is at Winfield, Missouri.
How the big programmes are counted: MoDOT's $2.8B Improve I-70 figure is the statewide programme appropriation (FY2024 budget) for Blue Springs to Wentzville. The Kansas City I-70 segment ($237M) is funded and contracted separately from that appropriation — MoDOT says so explicitly — so it is listed as its own record without double-counting. The same discipline applies at Lambert (only the awarded $114.92M airfield facility is listed, not the ~$3B terminal programme), at Whiteman AFB (only the awarded $74.9M hangar contract, not the ≈$900M B-21 beddown programme), and at Lock 25, where the listed $732M is the amount actually appropriated against a certified total need of ≈$2.26B — the gap is on the record.
News-flagged sources: six rows rest on news or trade-press reporting of official figures, flagged 'news-flagged' in the data — the KC Streetcar riverfront extension (Railway News, KC Streetcar Authority figures), UMKC's health sciences building (CEG, UMKC figures), the Jackson County Detention Center (Correctional News, county figures), Missouri State's Blunt Hall (Lab Design News), the Fort Leonard Wood hospital total (KY3, U.S. Army figures) and the Whiteman hangar award (the winning JV's release of a USACE award). Each record names the underlying official source. The NextGen MURR record is the softest on the page: only the $200M of state funding secured to date is tallied, against published total estimates of $1B–$1.2B.
Deliberately excluded: projects completed in a prior year, however large — the KC Streetcar Main Street Extension ($352M, opened October 2025), Next NGA West in St. Louis ($1.7B, opened September 2025), the Kansas City airport single terminal ($1.5B, opened 2023), the Buck O'Neil Bridge (opened 2024), the Rocheport I-70 Missouri River bridge (opened 2024) and the completed I-270 North design-build in St. Louis. Also excluded: Lambert's Consolidated Terminal Program (~$3B — still in design, airline approval for construction pending); the MetroLink extension to MidAmerica Airport, which is physically in Illinois and belongs to that state's page; private and nonprofit builds of any size (BJC, Children's Mercy, data centres, Boeing defence production) — out of scope by rule; and Missouri S&T's planning-stage capital items, for which no funded construction was verified.
