Most Concerning Texas Bridges: Poor Condition and High Traffic

The bridges of greatest concern combine a poor structural rating with high daily traffic loads. These Texas bridges carry the most vehicles per day while rated in poor condition:

How Texas Bridge Conditions Are Assessed

Bridge condition in the NBI is determined by ratings of three structural components — deck, superstructure, and substructure — on a scale of 0 (failed) to 9 (excellent). A bridge is classified as good when all three components score 7 or above. It is classified as poor when any component scores 4 or below. Ratings of 5 or 6 on any component with no component below 5 result in a fair classification. TxDOT coordinates inspections across Texas in line with FHWA standards, with most bridges inspected on a 24-month cycle.

Frequently Asked Questions

How many bridges in Texas are in poor condition?

680 of Texas’s 56,951 bridges are currently rated in poor condition by the FHWA National Bridge Inventory, a rate of 1.2%.

What is the oldest bridge in

The oldest bridge recorded in Texas’s NBI inventory is AVENUE A, built in 1900.

What does a poor bridge rating mean?

A poor rating means at least one of a bridge’s three key structural components — deck, superstructure, or substructure — has been rated 4 or below on the NBI 0-9 scale. A rating of 4 is defined as “poor condition,” and ratings of 3, 2, 1, or 0 indicate increasingly serious deterioration. Poor-rated bridges are not necessarily unsafe or closed, but they require priority attention and monitoring.
