Most Concerning Ohio Bridges: Poor Condition and High Traffic
The bridges of greatest concern combine a poor structural rating with high daily traffic loads. These Ohio bridges carry the most vehicles per day while rated in poor condition:
| Route / Facility | Crosses | Daily Traffic | Year Built | Deck | Superstructure | Substructure |
|---|---|---|---|---|---|---|
| IR 480 | CR 8 (LEE RD) | 142,337 vehicles/day | 1971 | Poor (4) | Satisfactory (6) | Satisfactory (6) |
| IR 90 | ROCKY RIVER VALLEY | 106,617 vehicles/day | 1971 | Good (7) | Poor (4) | Good (7) |
| 270WB to 71SB | RAMP 71NB-270WB | 104,140 vehicles/day | 1966 | Satisfactory (6) | Poor (4) | Fair (5) |
| I75 RAMP | DICKS CREEK | 91,260 vehicles/day | 1960 | N/A | N/A | N/A |
| IR 75 | TRIBUTARY MILL CREEK | 91,244 vehicles/day | 1960 | N/A | N/A | N/A |
How Ohio 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 Ohio in line with FHWA standards, with most bridges inspected on a 24-month cycle.
Frequently Asked Questions
How many bridges in Ohio are in poor condition?
1,266 of Ohio’s 26,713 bridges are currently rated in poor condition by the FHWA National Bridge Inventory, a rate of 4.7%.
What is the oldest bridge in
The oldest bridge recorded in Ohio’s NBI inventory is TR 75 REINHART RD, built in 1828.
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.
