About This Bridge
EASTGATE MALL ROAD carries traffic over INTERSTATE 805 & RAMPS in San Diego County, California. Built in 1971, this structure is 55 years old, placing it among the older bridges still in active service. The bridge features prestressed concrete continuous construction with a box beam - multiple design, a combination chosen by engineers to meet the specific requirements of this crossing.
Approximately 6,140 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. Commercial trucks account for 4% of all crossings. This proportion of commercial traffic is typical for this roadway classification and is factored into the bridge's design load ratings.
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 56 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.

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 5 indicates some deterioration that warrants monitoring but doesn't affect structural integrity.
For a structure built in 1971, this condition level is expected given the bridge's age and usage patterns.
Bridge Details
Prestressed Concrete 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.

Dimensions
Span dimensions affect structural design choices and load distribution. The deck area of 2,441 sq ft determines surface maintenance scope.

Projected Future ADT
Estimated future demand
This bridge carries approximately 6,140 vehicles per day, translating to roughly 2,241,100 crossings annually. Lower traffic volumes generally result in less structural wear over time.
Commercial trucks comprise 4% 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.
Traffic projections estimate future volumes of 7,702 vehicles daily, a 25% 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
10.0 tons
Maximum allowable load for special permits
Inventory Rating
3.2 tons
Load level for normal traffic
The operating rating of 10.0 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 3.2 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.
