Construction of the Golden Gate bridge began on January 5, 1933 under the Works Projects Administration (WPA), a program initiated by Franklin D. Roosevelt during
the Great Depression. It was completed in April 1937 and opened to pedestrians on
May 27 of that year. An estimated 200,000 people crossed. The next day, President Roosevelt pushed a button in Washington, D.C. signaling the start of vehicle traffic
over the Bridge. The cost to build it was $35 million.
