GOLDEN GATE IS REDECKED AT NIGHT
The $52.5-million project to replace the deteriorated concrete deck and steel stringers of the Golden Gate Bridge--while traffic keeps moving--is a nightly exercise in precision, with severe penalties for any misstep. Between 8:00 p.m. and 5:30 a.m. every week night, the contractor typically removes three 10 X 50-ft roadway sections--half of the 60-ft-wide deck--along with the adjacent sidewalk. In their place it installs two prefabricated, steel orthotropic plate panels and a precast lightweight-concrete sidewalk section. The original 7-in. concrete deck and 24-in.-deep stringers and diaphragms on the 47-year-old bridge are being replaced because of extensive corrosion caused by salt-laden fog that envelops it almost daily.
