Infrastructure Composites installs composite bridge in Illinois

Each of four sections of the bridge is 38 ft long and saves 70 to 80 in weight compared to concrete and steel structures.

Infrastructure Composites International (San Diego, Calif., USA) reports that it is building at its facility in Denver, Colo., an advanced composite bridge for the Illinois Department of Transportation (IDOT), and the city of Fairview Heights. The project is part of the Innovative Bridge Research and Construction (IBRC) program administered by the U.S. Federal Highway Administration. The program's objective is to evaluate and introduce these advanced materials and promising new technologies into the rehabilitation of the nation’s aging infrastructure. All four sections of this 38-ft/11.6m long composite vehicular bridge have been trucked to Illinois.

These lightweight composite bridges typically weigh 70 to 80 percent less than traditional steel or concrete bridges, making installing a complete bridge much faster, easier and less expensive. Furthermore, the bridges have a projected lifetime of 50 to 75 years. A prefabricated bridge like this can be installed at the site in one day, avoiding lengthy road shutdowns and traffic disruption with it’s associated costs.

In addition to complete bridges, this technology can also be used to put new decks on older bridges, making it possible to re-rate older bridges for a much greater traffic load than they were originally designed for. This solves a common problem with bridges built decades ago for lower load ratings.
