About This Bridge
IH 10 EB ENTR RP carries traffic over IH 10 EB EXIT RP 4-G in Harris County, Texas. Built in 2007, this structure is 19 years old, representing modern engineering and construction standards. The bridge features prestressed concrete construction with a stringer/multi-beam or girder design, a combination chosen by engineers to meet the specific requirements of this crossing.
Approximately 375,126 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 1% 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 good 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 156 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.
With a lowest rating of 7, this bridge demonstrates good condition meeting all safety standards.
For a structure built in 2007, maintaining good condition demonstrates effective maintenance practices.
Bridge Details
Prestressed Concrete is the primary structural material, which influences maintenance requirements and expected lifespan. The stringer/multi-beam or girder 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 3,804 sq ft determines surface maintenance scope.

Projected Future ADT
Estimated future demand
This bridge carries approximately 375,126 vehicles per day, translating to roughly 136,920,990 crossings annually. This high volume places significant demands on the structure and necessitates frequent inspections.
Commercial trucks comprise 1% 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 435,146 vehicles daily, a 16% 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
6.8 tons
Maximum allowable load for special permits
Inventory Rating
4.1 tons
Load level for normal traffic
The operating rating of 6.8 tons represents the absolute maximum load this bridge can carry under controlled conditions with special permits. The inventory rating of 4.1 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.
