About This Bridge
MILK HOUSE DRIVE carries traffic over DELAWARE CANAL in Bucks County, Pennsylvania. Built in 1832, this structure is 194 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 10 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 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 5 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 1832, 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 99 miles, underscoring the importance of maintaining this crossing.
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 State Park/Forest.

Dimensions
Span dimensions affect structural design choices and load distribution. The deck area of 56 sq ft determines surface maintenance scope.

Projected Future ADT
Estimated future demand
This bridge carries approximately 10 vehicles per day, translating to roughly 3,650 crossings annually. Lower traffic volumes generally result in less structural wear over time.
Traffic projections estimate future volumes of 15 vehicles daily, a 50% 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
0.9 tons
Maximum allowable load for special permits
Inventory Rating
0.6 tons
Load level for normal traffic
The operating rating of 0.9 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 0.6 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.
