Golden Gate Bridge: Deck Replacementby Daniel E. Mohn, Golden Gate Bridge Highway &, Transportation District, San, Francisco, CA, USA,
Abstract: A major inspection of the Golden Gate Bridge in 1968-69 found the reinforced concrete roadway of the Bridge to have widespread defects and local failures. Further investigations found that the concrete of the roadway contained a high level of chloride ion contamination and that the contamination was beyond the threshold limit. Therefore the existing roadway could not economically or practically be restored. Independent studies confirmed that complete replacement of the concrete roadway and its supporting members was economically preferable over rehabilitation of the existing concrete roadway.
