## Detailed answer

The construction of the Manhattan Bridge began in 1901, with the excavation of the bridge's foundations on both the Manhattan and Brooklyn sides. The construction process was complex and involved the use of innovative engineering techniques for the time, including the use of a 'deflection theory' to calculate the bridge's suspension system. The bridge was designed by Leon Moisseiff, a renowned engineer who would later go on to design other iconic bridges in New York City.
