Steve Lackmeyer and John Perry of The Oklahoman used state and federal data to find that "fixing Oklahoma's bridges — the nation's worst — would cost taxpayers billions of dollars. All proposed remedies fall woefully short." The state has had the highest percentage of structurally deficient bridges for at least three years. The bulk of such bridges are owned and maintained by county governments, which receive fuel tax revenues from the state for repair and upkeep. "Oklahoma has 140 bridges more than 80 years old. With the current funding structure, the agency can only replace about 324 bridges over the next decade. By that time, the state will have another 800 bridges more than 80 years old. The state has 199 highway bridges with either wooden structures or decking."
