About This Bridge

64 E Ramp to 264 E carries traffic over IS 264 WBL; 64 & Ramps in Norfolk city, Virginia. Built in 1985, this structure is 41 years old, built during a period of significant highway expansion. The bridge features steel continuous construction with a box beam - multiple design, a combination chosen by engineers to meet the specific requirements of this crossing.

Approximately 13,980 vehicles cross this bridge daily, representing moderate traffic volumes typical of important regional connectors. This level of usage requires regular monitoring to ensure continued safe operation.

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 124 feet, this structure falls within the typical range requiring standard inspection procedures conducted by certified bridge inspectors.

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.

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 1985, this condition level is expected given the bridge's age and usage patterns.

Bridge Details

Steel Continuous is the primary structural material, which influences maintenance requirements and expected lifespan. The box beam - multiple 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 13,980 vehicles per day, translating to roughly 5,102,700 crossings annually. This moderate traffic level is typical for regional connectors.

Traffic projections estimate future volumes of 20,412 vehicles daily, a 46% 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

9.0 tons

Maximum allowable load for special permits

Inventory Rating

7.3 tons

Load level for normal traffic

The operating rating of 9.0 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 7.3 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.

This data is for informational purposes only and should not be used for route clearance or vehicle weight decisions.
