- from Bridges
In 1810, about 3,000 people lived in Brooklyn, New York.
By 1850, more than 100,000 people lived there. To get to the island of Manhattan, they had to take a ferry across the East River. But the river often froze during the winter. Also, ferries were very crowded at rush hour. A new way of crossing was needed. In 1867, former Brooklyn Mayor Henry Cruse Murphy said a bridge would be a good idea. Two years later, construction began. It was to be one of the most amazing works of engineering ever.
