What surprising weather phenomenon did construction workers experience while building the bridge which created a rolling effect on the partially built structure. We'll be right back with these monumental answers after this break.

1:27 Welcome back, trivia fans. Let's reveal today's answers. Question one, in what year did the Golden gate Bridge open? Answer? Nineteen thirty seven. The bridge officially opened to pedestrians on May twenty seventh, nineteen thirty seven, and to vehicular traffic the following day. The opening celebration lasted for a week, with over two hundred thousand people crossing the bridge on foot. On opening day, President Franklin D. Roosevelt officially opened the bridge to traffic by pressing a telegraph key in the White House, which transmitted a signal to San Francisco. The bridge connected San Francisco to Marin County, eliminating the need for ferry service across the Golden Gate Strait and fundamentally transforming transportation in the Bay Area. Question two, What distinctive color is the bridge painted?

2:15 Answer? International orange. This reddish orange color was selected by consulting architect Irving Morrow because it complemented the natural surroundings while providing enhanced visibility in fog. The US Navy had initially wanted the bridge painted in black and yellow stripes to ensure visibility for passing ships. The color has become so iconic that it's officially known as Golden Gate Bridge International Orange and has a specific paint formula. The entire bridge is repainted continuously, with painters starting at one end and working their way across, then beginning again in a never ending cycle of maintenance. To protect the steel from the corrosive effects of salt Air.

2:59 Question three, how long did it take to construct the bridge? Answer? Four years and four months. Construction began on January fifth, nineteen thirty three, and was completed in April nineteen thirty seven, with the bridge opening to the public on May twenty seventh, nineteen thirty seven. This was an impressive feat. Considering the engineering challenges and the fact that it was built during the Great Depression. The project came in under budget at a cost of thirty five million dollars twenty seven million dollars for the actual bridge structure, which would be approximately one point five billion dollars in today's dollars. It was financed by a bond issue, with the debt being repaid through bridge tolls, which were initially set at fifty cents each way, equivalent to about ten dollars today.

3:48 Question four. Who was the chief engineer? Answer Joseph Strauss. Though he had never designed a suspension bridge before, Strauss championed the project for more than a dedaby deade against significant opposition. His initial design was heavily modified with the help of senior engineer Charles Alton Ellis and bridge designer Leon Moysief. Consulting architects Irving and Gertrude Morrow were responsible for the Art Deco elements and the distinctive color. Strauss remained the public face of the project and is widely credited as the driving force behind its completion. He wrote a poem titled the Mighty task is done for the bridge's opening, and died barely a year after its completion.

4:31 Question five, What surprising weather phenomenon did workers experience? Answer? An earthquake. On June twenty second, nineteen thirty six, during construction, workers experienced a rolling earthquake while on the bridge. The partially completed structure swayed significantly but suffered no damage, validating the flexible design that allowed it to move up to twenty seven feet Laterally, the bridge was specifically engineered to withstand strong winds and seismic activity, with flexibilit being a key component of its design. This flexibility was put to a much more serious test during the nineteen eighty nine Loma Prieta earthquake, when the Golden Gate Bridge swayed but remained intact while other Bay Area bridges, including a section of the Bay Bridge, suffered significant damage.
