According to History dot com it was on January 5, 1933, construction began on the Golden Gate Bridge, as workers began excavating 3.25 million cubic feet of dirt for the structure’s huge anchorages.  Following the Gold Rush boom that began in 1849, speculators realized the land north of San Francisco Bay would increase in value in direct proportion to its accessibility to the city. Soon, a plan was hatched to build a bridge that would span the Golden Gate, a narrow, 400-foot deep strait that serves as the mouth of the San Francisco Bay, connecting the San Francisco Peninsula with the southern end of Marin County.  The Golden Gate Bridge officially opened on May 27, 1937, the longest bridge span in the world at the time. The first public crossing had taken place the day before, when 200,000 people walked, ran and even roller skated over the new bridge.  The bridge cost 35 million dollars.  Listen to the podcast here; https://theriver953.com/lonnies-fun-fact/
