Project Overview

This project for the Union Pacific Railroad included removing an abandoned vertical lift bridge in Houma, Louisiana, transporting it more than 350 miles, and installing it at an existing swing bridge site in Freeport, Texas.

PCL refurbished the existing bridge machinery and control systems, and completed the dismantling and relocation efforts. The proposed vertical lift span included 200-foot steel vertical towers and a 258-foot lift span across the Old Brazos River in Freeport, Texas. New substructure and approaches were constructed around the existing deteriorating swing span structure in Freeport to allow for the new bridge, all while critical train traffic was maintained.

As the only rail line accommodating the Port of Freeport, this line had to remain undisturbed throughout construction. PCL provided the temporary works and engineering to allow for necessary modifications to the existing swing span and installation of the new lift span, and the team completed all track closings ahead of schedule.

Several unforeseen obstructions within the pier footprints were uncovered during substructure construction on the north side of the river. PCL worked with the client’s engineer to redesign the footing, and the team combined wire sawing and hydraulic hammers to expedite removal of a large concrete obstruction in the cofferdam, which saved the client critical construction time.
