A $600 million rebuild of Jackson's collapsed water system, a $400 million 'Big Fix' for the capital's interstate stack, a $250 million cancer centre rising at UMMC, and a wall of MDOT corridor work — I-10, I-55, SR 57, SR 67, U.S. 49 — headline a public pipeline that is smaller than its neighbours' but aimed at the state's most famous failures.
*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.

This is explicitly a MAJORS list. Mississippi publishes fewer programme-scale public projects than Batch 1's states, and dozens of funded MDOT, university and municipal jobs in the $10M–$70M range are not itemised; the 15 above are the state's sourced majors over the $10M floor with a published figure, a named public owner and a current status. The listed figures sum to ≈$2.3B — an order of magnitude below Georgia's ≈$41.2B, which is the honest shape of Mississippi's public pipeline, not a gap in the counting. MDOT owns 9 of the 15; Jackson alone holds 4 (the water rebuild, the Big Fix and both UMMC buildings).
Flagged sources: Ten rows rest on news or trade-press reporting of official figures, flagged 'news-flagged' in the data — the MDOT corridor jobs (Big Fix, SR 57, I-10, SR 67, I-59, U.S. 49, the welcome centre and I-55 Pike County, all from MDOT updates republished by Construction Equipment Guide / Mississippi Business Journal), I-55 DeSoto (Commercial Appeal reporting of the legislature's allocation and MDOT's estimate, plus the September 2026 INFRA award announcement) and the UMMC cancer centre (Jackson Wire reporting of UMMC's own campaign materials). One row (Ole Miss Jones Hall) rests on the contractor's own award release, flagged 'official-partner'. Owner-published and federal-record rows (JXN Water via EPA, UMMC Dentistry, the Port of Gulfport, the Stennis award record) are flagged accordingly.
Deliberately excluded: the Gulfport ship-channel deepening ($548M) — a signed Army Corps Chief's Report (June 2026) but no congressional authorisation or appropriation yet, so an unfunded proposal under this page's rules; the I-55 Madison County and SR 25 (Lakeland Drive) widenings (~$300M combined) — their funding bill died in the 2026 session and full funding was not in place at verification; Ole Miss's ~$1.3B campus programme total and Stennis's $120M site-wide authorisation — programme-level figures whose sub-projects would double-count (one named project from each is listed instead); private projects of any size (Ingalls Shipbuilding, the Amazon data centres and the Entergy power stations built to serve them, casinos, Relativity Space's Stennis build-out); and completed-in-prior-year majors (U.S. 82 Greenville Bypass Phase II, $79M, completed fall 2025; Mississippi State's $65M Duff Center, opened fall 2025). The proposed Jackson State stadium is an unfunded legislative proposal and is excluded on the same basis.
Softest record: the I-55 Pike County figure ('nearly $76M') and programme come from MDOT project reporting republished without a date on the page retrieved; the scope and 2027 completion are consistent across MDOT's southern-district updates, but the contract amount should be re-verified against MDOT's lettings on the next pass. The UMMC cancer centre's $250M is UMMC's campaign figure — a ~$350M supporter estimate reported the same week as groundbreaking is disclosed on that record, not adopted.
