ODOT cost reporting obscures 60% overrun on Oregon highway project, raising questions about transport transparency

The Oregon Department of Transportation (ODOT) has publicly celebrated a highway widening project near Salem as a budget success story, but a detailed analysis by urban policy research group City Observatory reveals the project actually ran more than 60 percent over its original cost estimate. The case illustrates how transport agencies can manipulate cost baselines to present overruns as achievements—a practice with direct relevance for infrastructure governance and public accountability anywhere major projects are delivered.

The project in question widened a southbound stretch of Interstate 5 between Kuebler Boulevard and Delaney Road near Salem, Oregon, adding a third lane over roughly two miles. In September 2026, ODOT announced the project was complete and under budget at $55.5 million, coming in $1 million below a revised $56 million price tag. Agency officials, including interim director Chris Warner and region manager Anna Hansen, praised the outcome as an “outstanding example” of good planning and problem solving.

The trouble, according to City Observatory’s analysis, is that the $55.5 million figure was not the project’s original budget. When the Oregon Transportation Commission approved the project in May 2018, the official staff report set the total cost at approximately $35.4 million, including engineering, right-of-way and construction. Construction alone was estimated at $25.6 million.

By July 2022, the commission approved a budget increase to $50.4 million, citing full-length widening to three lanes, bridge replacement, broadband installation and inflation. A further increase in 2024 brought the budget to more than $56 million. The cumulative increase from the 2018 estimate to the final cost represents a roughly 60 percent overrun on total project cost and about 77 percent on construction cost alone.

Key facts

ODOT’s public statements described the $55.5 million figure as the “initial” estimate, effectively erasing the earlier $35.4 million baseline. City Observatory argues this is a pattern of “re-baselining”—adjusting or ignoring original cost estimates to create the impression of fiscal discipline.

The reporting matters beyond Oregon because similar practices occur in transport agencies worldwide. When a major infrastructure project is approved, the original cost estimate is the benchmark against which taxpayers and elected officials judge performance. If agencies can quietly reset that benchmark each time costs rise, the public loses the ability to hold project sponsors accountable.

City Observatory notes that Oregon law (ORS 184.661) requires ODOT to compare actual spending to a project’s “original estimated cost.” The research group contends ODOT has violated this requirement by defining any increase under 10 percent as “on budget,” re-baselining original estimates, and omitting required figures from its project database. The agency has also been found to cite incorrect figures in response to public records requests about completed projects.

This is not an isolated incident. In 2016, ODOT hired a consultant to produce a report on a $110 million project that ended up costing $360 million; the consultant described the outcome as “27% higher than authorized amount,” a framing that City Observatory argues minimised the scale of the overrun. In June 2026, a report to the Oregon Transportation Commission on future liabilities for major projects cited incorrect cost ranges and omitted the state’s single largest project, according to the analysis.

The pattern matters for London readers because the mechanisms at play are not unique to Oregon. Transport for London, the GLA and borough councils all deliver large infrastructure programmes—from Crossrail to road schemes to cycle networks—where original cost estimates set public expectations. When those estimates prove inaccurate, the question of how agencies report and explain variance is a core governance issue.

In the UK, the Department for Transport’s Transport Appraisal Guidance requires that cost estimates be updated and reported transparently through the project lifecycle. Major programmes such as HS2 and Crossrail have faced scrutiny over cost escalation, and the National Audit Office regularly reviews how agencies manage and communicate budget changes. The Oregon case reinforces that the technical details of cost reporting—what baseline is used, how increases are categorised, whether original estimates remain visible—can determine whether the public sees a success or a failure.

For planners and transport professionals, the lesson is that “under budget” claims should always be checked against the original approved cost, not the most recently revised figure. For residents and campaigners, the case suggests that project monitoring should track the full cost history, not just the final number presented at completion.

The City Observatory analysis is based on Oregon Transportation Commission records from 2018, 2022 and 2024, as well as contemporaneous reporting from Salem Breakfast on Bikes and the Salem Reporter. The commission’s online archives do not include meetings prior to 2021, which the analysis notes made it harder to verify the original cost baseline without independent reporting.
