The advantages of the use of unpainted weathering steel for bridge construction is pointed out, and examples of its poor performance are attributed to its use in improper locations or conditions. In addition to the economic benefis that accrue from the elimination of the cost of the initial painting, there are substantial environmental benefits: reduction of the emission of volatile organic compounds when volatile-based coatings are specified; no coatings need be removed during maintenance and therefore no debris disposal problem. However, caution should be exercised in specifying weathering steel in marine areas, coastal areas, high rainfall and fog areas, industrial areas, grade separations in tunnel-like conditions, low level water crossings, and over sheltered water.
