Progress is underway on Corpus Christi, Texas’ Harbor Bridge project, with the project's social media page sharing images of the recently completed concrete placement on the first lift of the new cable-stayed bridge south tower, among other signifiers of things moving forward.

The bridge is to carry U.S. Route 181 across the Corpus Christi Ship Channel off Corpus Christi Bay, replacing the current Harbor Bridge, a through arch bridge that was built in 1959.

Harbor Bridge Project

According to the Caller Times, the original Harbor Bridge needed to be replaced due to having outlived its design.

The new bridge, to be constructed of concrete, will have a main span length of 1,661 feet, surpassing Louisiana’s John James Audubon Bridge as the longest cable-stayed bridge in the country. The joint venture Flatiron/Dragados LLC was chosen in 2015 by the Texas Department of Transportation for the design-build contract for the project.

The bridge’s main tower will be 538 feet tall, which the project team says will make it the tallest structure in South Texas. It will clear the water by 205 feet, an increase of 67 feet over the current bridge’s clearance, which will allow larger ships to pass into the Port of Corpus Christi.

According to Flatiron/Dragados’ plans, the bridge will be constructed with twin precast box girders with precast delta frames, creating maximum strength in extreme wind. Stays will be covered with white casings to provide a backdrop for a nighttime lighting display.

Project Progress

In the latest update, pictures show two of the tower cranes being used on the project. Each tower crane is to lift tower table segments and rebar cages as well as other materials needed to build both main towers. The update also notes: “Additional height will be added as the two main towers are constructed. The height of each main tower will reach approximately 535 feet, making this the tallest structure in South Texas.”

Crews have completed concrete placement on the first lift of the south tower; there will be 39 lifts total.

According to the Caller Times, the project broke ground in August 2016. Construction of the crosstown/interstate is slated for completion in early spring 2020, and the bridge is currently on track to be finished later that same season. Demolition of the current bridge will take place late 2021.
