Paddock Viaduct, Road bridge in Fort Worth, United States

Paddock Viaduct is a road bridge spanning the Trinity River in Fort Worth, connecting downtown to the northern areas of the city using reinforced concrete arch construction. The structure serves as a major transportation corridor and displays the engineering approach typical of its era.

The viaduct was constructed in 1914 by the engineering firm Brenneke and Fay to replace an inadequate suspension bridge from the 1890s. This new structure represented a major advancement in connecting the city's different areas.

The viaduct honours B. B. Paddock, a former state legislator and mayor of Fort Worth, whose name was attached to the crossing in 1980. Drivers and pedestrians on Main Street pass beneath concrete arches that have carried traffic since 1914, and the bridge is listed on the National Register of Historic Places.

The bridge remains open year-round for both vehicle and pedestrian traffic crossing the river. Regular maintenance work has been performed over the decades to keep the structure safe and usable.

The viaduct's 1914 arches were the first reinforced concrete arches in the United States to use self-supporting reinforcing steel, a method that let the steel frame carry the formwork during pouring. The bridge was added to the National Register of Historic Places on March 15, 1976.
