Corrosion Prevention for Extending the Service Life of Steel Bridges

One of the most often cited problems affecting not only the appearance, but more importantly, the structural integrity of steel bridges, is corrosion. This synthesis of current practices and existing knowledge seeks to provide a better understanding of how to combat the problem and extend the service life of aging and newly designed steel bridges. The primary approaches for gathering information were through a literature review and a survey of transportation agencies. The technical literature reviewed included “coated steels” and “uncoated steels.” Coated steel bridges were further divided by liquid coatings and metallic coatings (e.g., galvanizing and metallizing). Uncoated steels were predominately weathering-grade steels designed to form a protective rust layer (patina). The synthesis also reported on the use—although somewhat limited currently—of stainless steel for structural elements and various other components of bridge structures prone to corrosion. Forty-six state departments of transportation and three other bridge-owner agencies responded to the survey, which covered both maintenance and design. The survey addressed the challenges in making the optimal choices in design and maintenance, while recognizing that approaches will vary in different parts of the country.
