Editing Golden Gate Bridge (section)

===Bridge deck replacement (1982–1986)===
The original bridge used a [[concrete]] [[Deck (building)|deck]]. [[Salt]] carried by fog or mist reached the [[rebar]], causing [[corrosion]] and concrete [[spall]]ing. From 1982 to 1986, the original bridge deck, in 747 sections, was systematically replaced with a 40% lighter, and stronger, steel [[orthotropic deck]] panels, over 401 nights without closing the roadway completely to traffic. The roadway was also widened by two feet, resulting in outside curb lane width of 11 feet, instead of 10 feet for the inside lanes. This deck replacement was the bridge's greatest engineering project since it was built and cost over $68 million.<ref>{{cite web |title=Bridge Deck Replacement (1982–1986) |url=https://www.goldengate.org/bridge/bridge-maintenance/major-bridge-improvements/ |website=goldengate.org |access-date=August 2, 2020}}</ref>
