ODOT
Oklahoma • United States of America
The Oklahoma Department of Transportation (ODOT) manages approximately 12,000 miles of state highways in a state that serves as a major transit corridor between the Midwest and Texas, and the Southeast. Key freight corridors include I-35, I-40, I-44, I-244, and the Will Rogers Turnpike. Oklahoma's significant oil and gas industry generates substantial freight demand for oversized loads, pipeline equipment, and energy sector goods. ODOT administers commercial vehicle permits, manages weigh stations along major corridors, and provides the OK511 travel information system. The department also maintains the Turner and Will Rogers Turnpikes — critical toll routes for commercial freight carriers.
