Corrosion control for the Richmond/San Rafael Bridge

For the past 20 years, ensuring that structures can survive natural phenomena as well as everyday wear and tear has received greater emphasis. The estimated cost of achieving this two-tiered goal is nearing $200 billion a year in the U.S. alone. New materials and technology have caused the cost of construction and manufacturing to increase steadily. This article covers a seismic retrofit project that includes various corrosion control measures, including a special coating for steel exposed to sea air, the preservation of concrete in a saltwater environment, and the protection of concrete and steel exposed to subsea sediment.
