Longest Concrete Segmental Cable-Stayed Bridge in North America Opens in Texas

On June 28, the longest concrete segmental cable-stayed bridge in North America opened to traffic over the ship channel at the Port of Corpus Christi, Texas. The New Harbor Bridge, costing $1.3 billion, spans 1,004 meters with a main span of 506 meters and features a 164-meter tower, one of the tallest structures in southern Texas. Developed by Flatiron and Dragados, now a single entity, it replaces a 1959 bridge and supports larger maritime traffic at the U.S.’s largest crude oil port.

The new bridge, standing 62.5 meters above the water, accommodates Neo-Panamax container ships, a significant improvement over the old bridge’s 42-meter clearance. This upgrade enhances the port’s capacity to handle modern vessels, supporting regional trade and economic activity.

Planning for the bridge began with a public meeting in 2011, but the project faced delays due to design challenges. In 2020, FIGG Bridge Engineers was replaced by Arup (U.K.) and Carlos Fernandez Casado (Spain) following a federal investigation into a 2018 bridge collapse in Miami. In 2022, a third-party review raised safety concerns, leading to a resolution between the Texas Department of Transportation (TxDOT) and the developers in April 2023.

Local leaders highlighted the bridge’s economic impact. Corpus Christi mayor Paulette Guajardo stated: “This new bridge solidifies Corpus Christi’s position as a global energy hub.” Texas governor Greg Abbott said: “It’s a gateway for jobs, trade, and continued growth in the Coastal Bend.” The bridge strengthens infrastructure, fostering economic opportunities and improving connectivity for the port.

The New Harbor Bridge enhances maritime access, supports trade, and contributes to the region’s development as a key energy and shipping hub.
