Oklahoma in the Top Ten nationally
for highway bridge conditions

In August 2020, Gov. Kevin Stitt and Secretary of Transportation Tim Gatz announced that Oklahoma had become a Top Ten state nationally for highway bridge conditions. In September 2021, they announced the state had improved its Top Ten ranking from No. 9 to No. 7 in the nation. This ranking includes bridges on non-tolled interstates, U.S. highways and state highways maintained by the Oklahoma Department of Transportation.

Progress toward Top Ten

In 2004, Oklahoma ranked near the very bottom at 49^th nationally for highway bridge conditions.

In this year’s bridge conditions report submitted in April 2021, for the inspection year ending 2020, Oklahoma reported 67 structurally deficient or poor bridges on the highway system. This moved Oklahoma up to 7th place, keeping us a Top Ten State for bridges.

In this year’s bridge conditions report submitted in April 2021, for the inspection year ending 2020, Oklahoma moved up to 7th nationally.

Disclaimer: State rankings are based on a comparison of bridge condition data for bridges that are owned and maintained by State DOTs only as compiled by the Federal Highway Administration National Bridge Inventory.

Frequently Asked Questions

How many bridges does ODOT maintain?
ODOT is responsible for nearly 6,800 bridges on the highway system, which includes non-tolled interstates, U.S. highways and state highways.

What is a structurally deficient bridge?
A “structurally deficient” bridge requires significant maintenance and repair to remain in service and eventually will require major rehabilitation or replacement to address the structural health of the bridge.

Why do so many national reports say Oklahoma’s bridges are in poor shape?
Most national news reports combine all state, city and county roads and bridges together, even though they’re maintained by different levels of government. The State of Oklahoma is responsible for the 6,800 bridges on the highway system. There are nearly 16,000 bridges on local roads that are the responsibility of cities and counties.

How often are bridges inspected?
Federal law requires all bridges on public roads must be inspected at least once every other year. Some bridges are inspected more often depending on their condition.

Where does this bridge inspection data come from?
Federal law requires states oversee inspection of all bridges on public roads and report the data to the Federal Highway Administration each spring. ODOT, cities and counties have contracts with various engineering firms to conduct bridge inspections statewide.

How many structurally deficient bridges has ODOT addressed since 2004?
While addressing the 1,168 structurally deficient bridges identified in 2004, ODOT also performed work on hundreds of additional bridges that became deficient. ODOT has replaced or rehabbed nearly 1,600 total structurally deficient bridges since 2004, with 67 remaining on the highway system.

Does these mean ODOT is finished with highway bridges?
Absolutely not! All bridges must be properly maintained after construction to remain in good condition. Additionally, more than 1,000 existing highway bridges are 80 years old or older and must be addressed in the coming years; however, ODOT now has a sustainable plan in place to maintain its bridges.

What’s being done about city and county bridges?
Local bridges not on the highway system are under the jurisdiction of cities and counties, which receive state motor fuel tax and motor vehicle collections revenue and have access to some federal funds, as well as local tax revenue. In 2006, the Legislature created the County Improvements for Roads and Bridges (CIRB) program, which provides designated state funding for high-priority county projects that no single county could fund on its own. ODOT administers those funds and provides assistancee leveraging federal funding for maximum benefit.
