Texas Historic Bridges on the National Register of Historic Places
Texas possesses a rich architectural legacy reflected in its diverse array of historic bridges. From the early iron trusses of the late 19th century to the sweeping concrete arches of the mid-20th century, these structures serve as vital links to the state's industrial and transportation evolution. Many of these landmarks are officially recognized on the National Register of Historic Places, ensuring their significance is documented for future generations.
These bridges represent a variety of engineering solutions designed to conquer the challenging geography of the Lone Star State, crossing everything from the mighty Colorado River to small bayous in urban centers like Houston.

- Loss of Heritage: Some listed bridges, such as the Angelina River Bridge and the State Highway 34 Bridge, have been demolished.
Engineering and Bridge Types
The bridges listed on the National Register showcase the progression of materials and design. The truss bridge, characterized by a framework of connected elements forming triangular units, is particularly prevalent in Texas history.
Truss Variations
Several specific truss designs appear frequently in the Texas registry:
- Parker Through Truss: A design with a curved upper chord, seen in the Brazoria Bridge and numerous State Highway bridges.
- Pratt Through Truss: A common 19th-century design used in the Cummins Creek Bridge and Lone Wolf Crossing Bridge.
- Warren Pony Truss: A truss where the structure does not extend above the deck, utilized in the Beaver Creek Bridge.
Arches and Suspensions
Beyond trusses, Texas features impressive masonry and concrete work. The concrete arch, known for its strength and aesthetic appeal, is found in the Houston Street Viaduct and the San Jacinto Street Bridge. Additionally, suspension bridges, which use cables to support the deck, are represented by the historic Waco Suspension Bridge and the Regency Suspension Bridge.
