When were the twin towers erected?

Answer 1

20 years

The initial concept dates back to 1946 for a "World Trade Center" Development. There were numerous delays for a variety of reasons. However, demolition did not actually began until March 1966. The first tenants moved into the north tower in Dec 1970 with the first tenants moving into the south tower in Jan 1972. The ribbon cutting ceremony was in April 1973.

Answer 2

The first ideas about creating the world trade centers began in 1946, when the project was first proposed. However initial plans weren't released until 1961. At this point planning was halted, for the construction required approval from not only the eager governor of New York, but also the unwilling Governor of New Jersey. Finally in 1966 an agreement was made between the involved parties, the two governors, the mayor of New York, the New York City Council and the construction company the Port Authority Trans-Hudson (PATH). Shortly there after in 1966 groundbreaking of the construction began. For another four years construction on the two main towers continued, until on December 23 1970, the north tower's (Tower one) topping ceremony was held. The south tower's (tower two) topping ceremony was held nearly a year later on July 19, 1971. Finally the final ribbon cutting ceremony was held on April 4, 1973 at which point the towers were officially opened.
