Norkfolk Southern – 201.0w Hunley Creek Bridge 2020
The Situation
The existing structure was a steel beam bridge with a steel ballast deck on steel H-piles. The proposed structure included a 96’ long welded through Plate Girder Span, and weighed approximately 384 tons. The new structure also needed to be raised 3 feet in order to alleviate flooding.
Why They Hired Cooper Contracting
Our reputation boasts not only a priority on safety and excellence, but also timeliness. As a planned outage was going to be necessary for this project, Cooper Contracting was the best fit for the job.

Our Solution
Due to the sheer size of the structure, the span had to be rolled into place during a planned track outage. We also planned for a 2-foot track raise to be completed concurrently with the installation of the new structure. This project was not only completed to our standards of excellence; it was completed early. We’d planned a 17-hour track outage to raise the track and completely replace the existing structure, but work was complete by hour 12.
