Super•Cor structure barges into remote Alaskan island

February 19, 2014

When Big R goes the distance on being competitive, we don’t fool around.


In this case, we trucked a Super•Cor Box Culvert from our Mansfield, TX plant to Seattle, WA in order to catch a barge up to Thorne Bay — on Prince of Wales Island in South East Alaska — only to be trucked again across the Island to the community of Craig.


More cost effective than conventional beam bridge

All this, and it was still a more cost-effective solution to a conventional beam bridge from a closer manufacturer. Plus, it offered a smaller footprint solution with less impact on the stream’s habitat. By all accounts, it was the right bridge for the job.

The right bridge, had to be built right

Because of the scheduled barge journey and the remoteness of the site, everything had to be right. A quick response from our in-house engineering department offered a choice of solutions for the contractor and construction engineer. We coordinated geometry with the headwall designer and shipping with the owner’s barge company.

No fishing for compliments here

The project partners were very pleased at how easily and quickly the structure went together and they were equally impressed with its strength and stiffness when backfilling. We learned all this on the fishing trip they invited us on after the work was done.
