FAMED GOLDEN GATE SPAN UNDERGOES COMPLEX SEISMIC REVAMP : DEMANDING AND WELL-CHOREOGRAPHED OPERATION IS PART OF A PLANNED THREE-PART RETROFIT

This article profiles ongoing seismic revamping on the Golden Gate Bridge, focusing on the placement of new pylons, supporting a temporary new viaduct and time constraints for tourism. The author lists basic specifics of the project such as cause, cost, and timeframe, and various project-specific roadblocks such as weather, water and danger. A pylon plating detail illustrates the scope and challenges of reinforcing the key bridge segment and actual methodologies for strengthening the pylon are discussed. Another diagram illustrates a section on viaduct temporary support, which will hold up the roadway while existing towers are replaced. Specific hardware and methods are explained, as well as time delays experienced. Lastly, the article explores time limitations caused by tourism and weather, focusing on the four-day work-week and the changeable fog conditions, which affect dew points and painting applications.
