Oklahoma moves into the Top Ten nationally
for highway bridge conditions
On Aug. 13, 2020, Gov. Kevin Stitt and Secretary of Transportation Tim Gatz announced that Oklahoma has become a Top Ten state nationally for highway bridge conditions. This includes bridges on non-tolled interstates, U.S. highways and state highways maintained by the Oklahoma Department of Transportation.
Progress toward 2020
In 2004, Oklahoma was ranked 49th nationally for highway bridge conditions. In last year’s bridge conditions report submitted to the Federal Highway Administration in April 2019, for the inspection year ending 2018, Oklahoma reported 132 structurally deficient or poor bridges out of the 6,749 on the highway system. This placed Oklahoma at 13th place, just outside of the Top Ten.
In this year’s bridge conditions report submitted in April 2020, for the inspection year ending 2019, Oklahoma reported 86 structurally deficient or poor bridges on the highway system. This moved Oklahoma to 9th place, a Top Ten State.

Timeline of Bridge Progress

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 to 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. Nearly 1,600 total structurally deficient bridges have been replaced or rehabilitated since 2004, with 86 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 administered by ODOT for high-priority county projects that no single county could fund on its own.
