About This Bridge

KREPPS BRIDGE T799 carries traffic over RACCOON CREEK in Washington County, Pennsylvania. Built in 1887, this structure is 139 years old, making it a historic structure that has served the community for generations. The bridge features wood or timber construction with a truss - thru design, a combination chosen by engineers to meet the specific requirements of this crossing.

Approximately 40 vehicles cross this bridge daily, indicating lower traffic volumes common for local roads and rural routes. While traffic is lighter, these bridges still serve essential community transportation needs.

The bridge is currently rated in poor condition based on federal inspection criteria established by the Federal Highway Administration. It is classified as structurally deficient, meaning one or more components have received a rating of 4 or below on the 0-9 scale. This designation indicates significant deterioration that warrants attention, though the bridge remains safe for travel within its posted limits. Structurally deficient does not mean unsafe—rather, it signals that repairs or replacement should be prioritized in transportation planning. With a total length of 3 feet, this is a shorter span typical of local road crossings, often carrying traffic over small streams, drainage channels, or other roadways.

The construction materials used in this bridge were selected based on engineering requirements, cost considerations, and local conditions at the time of construction.

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.

Condition Ratings

Structurally Deficient

This bridge has one or more component ratings of 4 or below, indicating significant deterioration that requires attention. The bridge remains safe for travel but may have load restrictions.

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 superstructure rating of 4 shows advanced deterioration in beams or girders. The substructure rating of 4 reflects significant wear in piers, abutments, or foundations.

For a structure built in 1887, the current condition reflects the cumulative effects of age, traffic, and environmental exposure.

Bridge Details

Wood or Timber is the primary structural material, which influences maintenance requirements and expected lifespan. The truss - thru design was selected based on span requirements, load capacity needs, and site conditions at the time of construction. Maintenance responsibility falls to County Highway Agency.

Projected Future ADT

Estimated future demand

This bridge carries approximately 40 vehicles per day, translating to roughly 14,600 crossings annually. Lower traffic volumes generally result in less structural wear over time.

Traffic projections estimate future volumes of 40 vehicles daily, a decrease 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

1.8 tons

Maximum allowable load for special permits

Inventory Rating

1.3 tons

Load level for normal traffic

The operating rating of 1.8 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 1.3 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.
