Texas Bridge Infrastructure: A Comprehensive Analysis

Texas is home to 56,951 bridges spanning 252 counties, making it one of the most significant bridge inventories in the country. These bridges carry a combined 648,207,427 vehicle crossings every day. Here is a comprehensive look at the state of Texas's bridge infrastructure based on the latest National Bridge Inventory data.

Texas earns an overall infrastructure grade of A based on the percentage of its bridges in poor condition. Currently, 680 bridges (1.2%) are rated poor, compared to the national average of 6.7%. The average bridge in Texas is 45 years old, younger than the national average of 48 years.

Of the state's 56,951 bridges, 29,423 are in good condition, 26,848 are fair, and 680 are poor. View the full breakdown on the [Texas report card](/reports/texas).

These are the bridges carrying the highest daily traffic volumes across Texas. High-traffic bridges are critical infrastructure -- their condition directly affects the commutes of tens of thousands of drivers.

The following bridges have the lowest sufficiency ratings in Texas. These structures are the most likely candidates for federal repair or replacement funding under the Bipartisan Infrastructure Law.

Texas's oldest bridges tell the story of the state's transportation history. Some of these structures have been in continuous service for over a century.

Texas's bridge infrastructure grade of A reflects both the current condition of the state's bridges and the scale of the challenge ahead. With an average bridge age of 45 years, many of these structures are approaching or past the 50-75 year design life typical of most bridges. The state's ability to maintain and replace aging bridges will determine whether conditions improve or deteriorate in the coming decade.
