Thanks to a 'vertical assembly line,' Millennium Tower is well on its way to completion.
The tower will rise 60 stories and 685 feet, a process that will take a little more than three years to build. With Suffolk Construction expertly coordinating 500 workers, the Tower is now growing by two floors per week as lower floors receiving finishing touches. By this time next year, the condominiums on the lower floors should be occupied by the building's new residents.
