POSTMORTEM OF A FAILED BRIDGE

Abstract

Much of the research that is responsible for extending the service life of new and existing bridges is less than 10 years old. Reinforced concrete bridges built 40 to 70 years ago were not built with any of the technological advantages for combatting corrosion damage as are now used in modern bridges. Maintenance and repair efforts reflected the construction practices of that earlier period. Today many of these older bridges are still in service along the Oregon coast and in sound condition. The purpose of this article is to examine the reasons it was necessary to replace one bridge, the Rocky Point Viaduct, after a service life shorter than that of other bridges built during the same time period. The maintenance and repair history of this bridge is documented in this article. A postmortem analysis of one beam from the bridge is presented.
