Oklahoma Department of Transportation (ODOT) announced the delay or cancellation of dozens of projects on Oct. 6, citing the impact of inflation and federal funding certainty.

As Director Tim Gatz submitted the new eight-year work plan for approval by the Oklahoma Transportation Commission, he acknowledged that several key projects—though high priorities for the state—may not be completed within the plan’s timeframe.

One of the main challenges he cited is the uncertainty surrounding the renewal of the federal transportation funding bill in 2026, which makes long-term financial planning difficult. According to Gatz, federal funds account for 50 to 60 percent of Oklahoma’s capital outlays.

Compounding the issue is the rising cost of highway construction. The National Highway Construction Cost Index (NHCCI)—the Federal Highway Administration’s measure of inflation in the sector—has climbed more than 63 percent. While cost increases are beginning to level off, volatility in the heavy highway construction market remains a concern.

At the same time, Oklahoma’s highway system is facing a $27 billion shortfall just to reach acceptable standards, with infrastructure needs exceeding the agency’s capacity to deliver improvements.

The Commission approved ODOT’s new Eight-Year Construction Work Plan for nearly $8 billion in transportation projects throughout the state.
