Mohawk skywalkers is a nickname for Mohawk ironworkers and other construction workers who have helped construct buildings and bridges in American and Canadian cities including New York City, Chicago, Philadelphia, San Francisco, Detroit, Toronto, Vancouver, and Montreal. Mohawk workers have contributed to the construction of iconic structures across North America including the Empire State Building, the Chrysler Building, Sears Tower, the CN Tower, the Brooklyn Bridge, the Golden Gate Bridge, the San Francisco Bay Bridge, the George Washington Bridge, the United Nations Building, and the Twin Towers. Mohawk volunteers and workers contributed to both rescue efforts at Ground Zero and the rebuilding of the new World Trade Center.
