"Mohawk high-steel men worked on virtually every big construction project in New York City: the Empire State Building, the RCA Building, the Daily News Building, the Bank of Manhattan Building, the Chrysler Building, the United Nations, and Madison Square Garden. They also continued to build bridges, including the George Washington Bridge, the Bayonne Bridge, the Triborough Bridge, the Henry Hudson Bridge, the Hell’s Gate Bridge, the Bronx-Whitestone Bridge, and many more."
