The Century Challenge

Corrosion is a serious issue in bridge design. Corrosion can impair the long-term function and integrity of the structure of a steel bridge. Engineers have developed a variety of coatings that can protect steel surfaces from the elements. This coatings are critical for the durability and integrity of bridge structures. Most coating lasts about thirty years before major maintenance is required. Researchers at the Federal Highway Administration (FHWA) are working to improve the service life of bridge coatings. A study from FHWA’s Coatings and Corrosion Laboratory worked to identify a coating system that could last for a hundred years with almost no maintenance. The study did not find any coating that filled this qualification.
