Abstract:

Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with corrosion promoting chlorides. Engineers determined that the deck could not be salvaged, and had it replaced. Replacement had to be done at night, so that traffic would not be interfered with. To accomplish this, the deck was replaced with prefabricated orthotropic steel panels. A few were installed each night, and opened to traffic in time for the morning rush hour.
