A $2.56 billion water plant for Portland, a $2.15 billion airport terminal finished in June, two Columbia River crossings, a new cancer tower at OHSU and capitol seismic work headline Oregon'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.

Oregon's page lists 17 public projects with a combined ≈$12.02B in published figures (range-priced projects counted at the low end, disclosed in their records). The rules: buildings and infrastructure owned by federal, state, public-university, public-health, city/county or tribal bodies (tribal governments are in-scope owners under the owner's October 26, 2026 ruling, where the tribe is the documented owner or federal grant recipient); a published figure above $10M required; projects completed earlier in 2026 are listed as completed with their opening dates, while 2025-and-earlier completions are named below with figures instead.
Two Columbia River crossings, two treatments. The Interstate Bridge Replacement Program (I-5 between Portland and Vancouver) is listed on WASHINGTON's page at its published total: its estimate stood at $5–$7.5B until the program's June 2026 financial plan raised the range to $13.5–$15.2B (probability-weighted figure $14.412B), with a funded first phase of $4.7–$6.2B; Oregon carries this pointer only. The Hood River–White Salmon Bridge Replacement (or-004) is listed HERE at its published $1.12B total, because the bi-state bridge authority's project office is in Hood River, Oregon; Washington's $125M share is disclosed in that record.
Excluded and named — completed before 2026: OR 217 Auxiliary Lanes ($174M, completed November 12, 2025); A Better Red, TriMet's MAX Red Line extension ($215M, opened August 28, 2024); TriMet's Division Transit Project (FX Division Line, opened 2022); Benson Polytechnic High School modernization ($410M+, completed 2024); the University of Oregon's Heritage Project — University and Villard Halls (≈$96M, reopened September 2025); and OSU-Cascades' Student Success Center ($21.75M, completed 2025). Excluded and named — terminated: the Columbia River Crossing, the I-5 bridge program abandoned in 2014 after nearly $200M of planning on a roughly $3B project, when Washington declined to authorize its share after Oregon authorized $450M in 2013. It is recorded as terminated, never as suspended. Also excluded: the Willamette Falls Locks, whose federal seismic upgrade cost only $4.3M and finished in April 2024 (below this page's floor and prior-year), with no clean published total for full restoration; and the Oregon State Hospital, which has no priced current major project (2025 legislation carried only $2.675M of capital improvements).
Tribal-government projects — two listed, under the owner's October 26, 2026 scope ruling (tribal governments are in-scope owners where the tribe is the documented project owner or federal grant recipient). Confederated Tribes of Warm Springs — new water treatment plant: LISTED (or-016) at its committed federal funding of $28,863,000 — more than $23M fully funded under a May 22, 2023 EPA/Indian Health Service agreement (IHS $13,601,000 + EPA $10,262,000, mostly Bipartisan Infrastructure Law money), plus $5M of congressionally directed funding; design began in 2023; the plant replaces a 1981 facility and serves about 3,800 people, while tribal utility staff have put the wider water-system need (pipes and distribution) at $100M+. Confederated Tribes of Grand Ronde — Resident & Recreation Center: LISTED (or-017) at $22M, the low end of the Tribe's published $22–$25.5M cost estimate, for a 45,000 sq ft center on the Smith Property at Tyee Road, across from the Tribal Housing Department offices. Its record discloses the funding story in full: a $20M EPA Community Change Grant (Inflation Reduction Act) awarded in December 2024 took the Tribe's secured funding to $27.5M ($22.5M of grants plus $5M budgeted by Tribal Council), but the funding agreement was terminated in January 2025 after the change of federal administration; design was nearly complete in May 2026 and the Tribe is fundraising to close the gap. Also documented for the Tribe: its Early Care and Education Center, completed in March 2025 at approximately $16M (26,000 sq ft, 140 children; named APWA Oregon 2025 Project of the Year in its class) — a prior-year completion, so named here rather than listed; and its tumwata village demolition at the former Blue Heron Paper Mill in Oregon City, about 75% complete as of May 2026, with no figure published.
Private and planning-stage exclusions: Oregon's largest construction is private and off this page by rule — Intel's semiconductor fabs, and the data-center campuses of Amazon, Google, Meta, Apple and xAI, along with private hospital and resort builds. Named but not listed because no construction decision or current price is published: OSU-Cascades' Student Health & Recreation Center ($84M in earlier asks — $22M land reclamation plus $62M building, seeking $42M state — and $95M in OSU's March 2026 ten-year capital forecast), and OSU's Hatfield Marine Science Center Building 900 replacement (a $70–$82M range in the same forecast only). The softest listed records are Jefferson High School (or-008, pre-construction with its delivery model under review), the Medford terminal (or-014, a concept-stage budget in design), the Rose Quarter (or-003, later phases unfunded) and I-205 (or-005, where an emerging $885M figure exceeds the counted $815M program total) — each flagged in its own record.
