For the US 181 Harbor Bridge replacement project in Corpus Christi, TX the two main pylons feature 538-foot towers which are currently partially constructed. Each pylon is supported by 21 shafts measuring 10 feet in diameter, drilled to a depth of 230 feet which were installed by A.H. Beck in 2017/2018. A.H. Beck was brought back in 2023 to install additional shafts to supplement the existing pylon foundations. 48-inch diameter shafts along the north and south perimeter of the pylon footings were installed each to a depth of 230 feet. The shafts were installed underneath previously constructed portions of the bridge deck and in coordination with the ongoing construction of the pylon and bridge deck erection.
