Golden Gate Bridge, San Francisco, California.
January 5, 1933: Official start of Golden Gate Bridge construction.
May 28, 1937: Golden Gate Bridge opens to traffic at twelve o'clock noon, when President Franklin D. Roosevelt pressed a telegraph key in the White House to announce the event to the world. When FDR pressed the telegraph key, every fire siren in San Francisco and Marin was sounded, every church bell rang, ships sounded their whistles, and every fog horn blew. The Bridge opened ahead of schedule and under budget.
