The project involves the replacement of the current US 181 Harbor Bridge in Corpus Christi, Texas, along with a change in the alignment to interchange between US 181 and Interstate 37. The current bridge does not provide enough clearance for select ocean bound ships traveling to-and-from Corpus Christi Bay and the Port of Corpus Christi from the Gulf of Mexico.

Designed and constructed by Flatiron and Dragados in a joint venture, the new Harbor Bridge accommodates larger ships and will be the longest cable-stay bridge in the U.S. and Canada when completed. The old bridge will be demolished, making way for the new, six-lane bridge (3-lanes in each direction, as well as a bike/pedestrian path).

Its main span length is 1,661 feet and the base of each bridge tower is roughly the size of a basketball court. The length of the main span of the bridge is equivalent to the length of five and a half football fields and the bridge itself has more than 862 miles of strand in the cable-stays. Along with the bridge, the project also involves reconstruction of portions of US 181, I-37, and a nearby expressway. Overall, nearly 6.5 miles of bridge and connecting roadway will be designed and constructed.

The Record of Decision was published in January 2016. TxDOT entered into a four-party agreement with the City of Corpus Christi, the Federal Highway Administration, and the Port of Corpus Christi.
