Golden Gate Bridge
In 1930, people in San Francisco and Marin County agreed that the local governments could sell bonds to the public to raise money for the bridge. The new bridge was going to cost $30.1 million.  But it was difficult for the governments to sell the bonds at the time because of the Wall Street Crash of 1929.  Finally, the Bank of America, which was based in San Francisco, agreed to buy all the bonds to help the local economy.
