About This Bridge

IR 280 carries traffic over MAUMEE RIVER and NSRR in Lucas County, Ohio. Built in 2007, this structure is 19 years old, representing modern engineering and construction standards. The bridge features concrete construction with a cable-stayed design, a combination chosen by engineers to meet the specific requirements of this crossing.

Approximately 57,927 vehicles cross this bridge daily, making it a high-traffic corridor critical to regional transportation. Bridges carrying this volume require enhanced inspection schedules and proactive maintenance programs. Commercial trucks account for 16% of all crossings. This heavy commercial usage significantly impacts structural wear, as a single fully-loaded truck can cause as much deck wear as thousands of passenger vehicles. Transportation planners factor this into maintenance scheduling and budget allocation.

The bridge is currently rated in fair condition based on federal inspection criteria established by the Federal Highway Administration. The structure meets current safety standards for its designated use and load capacity. With a total length of 153 feet, this structure falls within the typical range requiring standard inspection procedures conducted by certified bridge inspectors.

Concrete bridges offer excellent durability and relatively low maintenance requirements. They resist corrosion well but can develop cracking over time, particularly in regions with freeze-thaw cycles or heavy use of deicing chemicals. Regular inspection focuses on detecting cracks, spalling, and reinforcement corrosion.

Federal law requires that all highway bridges be inspected at least every 24 months by qualified inspectors following the National Bridge Inspection Standards (NBIS). Some bridges with known issues or unusual characteristics may be inspected more frequently. Inspection data is reported to the National Bridge Inventory, a database maintained by the Federal Highway Administration that tracks the condition of all public highway bridges in the United States. This bridge data is sourced from that federal database and reflects the most recent available inspection results.

Lowest Rating

Determines condition category

NBI condition ratings range from 0 (failed) to 9 (excellent). Ratings of 4 or below are considered poor. The overall condition category is determined by the lowest individual component rating.

The fair condition rating of 6 indicates satisfactory condition with minor section loss or deterioration.

For a structure built in 2007, this condition level is expected given the bridge's age and usage patterns. If this bridge were closed, traffic would face a detour of approximately 10 miles, underscoring the importance of maintaining this crossing.

Bridge Details

Concrete is the primary structural material, which influences maintenance requirements and expected lifespan. The cable-stayed design was selected based on span requirements, load capacity needs, and site conditions at the time of construction. Maintenance responsibility falls to State Highway Agency.

Projected Future ADT

Estimated future demand

This bridge carries approximately 57,927 vehicles per day, translating to roughly 21,143,355 crossings annually. This high volume places significant demands on the structure and necessitates frequent inspections.

Commercial trucks comprise 16% of traffic. Heavy vehicles cause disproportionate wear—a single fully loaded truck can have the impact of thousands of passenger cars on bridge deck surfaces. This high percentage of truck traffic may accelerate deterioration of deck surfaces and structural components.

Traffic projections estimate future volumes of 80,403 vehicles daily, a 39% increase from current levels. These projections inform capacity planning and potential upgrade requirements.

Load Ratings

Load ratings determine what weight this bridge can safely support. These values are critical for routing heavy vehicles and issuing overweight permits.

Operating Rating

7.5 tons

Maximum allowable load for special permits

Inventory Rating

4.2 tons

Load level for normal traffic

The operating rating of 7.5 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 4.2 tons is the safe load limit for everyday traffic without restrictions. These relatively low ratings may result in posted weight limits or route restrictions for heavy vehicles.

Bridge inspection data is typically updated every 24 months. Conditions may have changed since the last inspection.

“Structurally deficient” does not mean a bridge is unsafe or likely to collapse. It indicates that one or more key structural elements are in poor or worse condition. Bridges are inspected regularly and may have load restrictions in place.
