Oklahoma state auditor releases investigative audit findings on Turnpike Authority after Attorney General’s 2023 request

Audit findings follow years of scrutiny over governance, finances and transparency

Oklahoma’s State Auditor and Inspector, Cindy Byrd, released the findings of an investigative audit of the Oklahoma Turnpike Authority (OTA) on March 4, 2026, marking a significant milestone in a review sought by state leaders amid longstanding questions about the agency’s financial practices and public accountability.

The audit was requested by Attorney General Gentner Drummond on March 15, 2023, shortly after he took office. In his written request, Drummond cited concerns raised by legislators, community leaders, private citizens and state employees, including questions about transfers between OTA and the Oklahoma Department of Transportation, contracting and purchasing practices, and the adequacy of internal financial controls. The request also referenced a district court finding that OTA “willfully” violated the Open Meetings Act in a December 2022 ruling.

What state leaders said the audit did — and did not — find

In a public response issued the same day the findings were released, Drummond said the investigative audit did not uncover criminal misconduct. He also said the absence of criminal findings should not be interpreted as a comprehensive endorsement of the agency’s operations, emphasizing a need for greater oversight, accountability and transparency.

Drummond pointed specifically to the prior Open Meetings Act ruling as a marker of broader governance risk, describing willful violations as more than technical errors. He said his office would continue monitoring OTA operations and would act if future conduct warranted further review.

How the investigative audit fits into broader oversight of the Turnpike Authority

The investigative audit is distinct from the financial-statement audits OTA undergoes annually. OTA’s annual audit requirement is embedded in state law and the agency’s trust agreement, and those audits are performed by an independent public accounting firm as part of routine financial reporting.

Separately, legislative oversight of Oklahoma’s toll-road system has also intensified in recent years. In October 2025, the Oklahoma Legislative Office of Fiscal Transparency published an evaluation focused on the cost of Oklahoma’s toll roads, adding another layer to the public record surrounding OTA operations and the toll-financed model.

Key context and timeline

• December 2022: A district court found OTA “willfully” violated the Open Meetings Act.

• March 15, 2023: The attorney general formally requested an investigative audit of OTA, citing concerns about financial conduct, contracting, internal controls and transfers involving transportation entities.

• October 2025: A statewide evaluation of toll-road costs was published by the Legislative Office of Fiscal Transparency.

• March 4, 2026: The state auditor released investigative audit findings; the attorney general issued a statement describing no criminal misconduct but calling for stronger oversight and transparency.

The investigative audit’s release places renewed attention on how OTA governs major transportation decisions, handles public-meeting requirements, and documents financial and operational practices — issues that remain central to debates over accountability for toll-funded infrastructure.

Further actions stemming from the findings are expected to hinge on whether policymakers pursue additional statutory guardrails, enhanced reporting requirements, or other oversight mechanisms tied to OTA governance and transparency.
