Most Concerning Oklahoma Bridges: Poor Condition and High Traffic
The bridges of greatest concern combine a poor structural rating with high daily traffic loads. These Oklahoma bridges carry the most vehicles per day while rated in poor condition:
| Route / Facility | Crosses | Daily Traffic | Year Built | Deck | Superstructure | Substructure |
|---|---|---|---|---|---|---|
| I-240 | I-35 UNDER | 99,100 vehicles/day | 1959 | Fair (5) | Fair (5) | Poor (4) |

How Oklahoma Bridge Conditions Are Assessed
Bridge condition in the NBI is determined by ratings of three structural components — deck, superstructure, and substructure — on a scale of 0 (failed) to 9 (excellent). A bridge is classified as good when all three components score 7 or above. It is classified as poor when any component scores 4 or below. Ratings of 5 or 6 on any component with no component below 5 result in a fair classification. ODOT coordinates inspections across Oklahoma in line with FHWA standards, with most bridges inspected on a 24-month cycle.
Frequently Asked Questions
How many bridges in Oklahoma are in poor condition?
1,719 of Oklahoma’s 22,926 bridges are currently rated in poor condition by the FHWA National Bridge Inventory, a rate of 7.5%.
What is the oldest bridge in
The oldest bridge recorded in Oklahoma’s NBI inventory is E2080, built in 1900.
What does a poor bridge rating mean?
A poor rating means at least one of a bridge’s three key structural components — deck, superstructure, or substructure — has been rated 4 or below on the NBI 0-9 scale. A rating of 4 is defined as “poor condition,” and ratings of 3, 2, 1, or 0 indicate increasingly serious deterioration. Poor-rated bridges are not necessarily unsafe or closed, but they require priority attention and monitoring.
