CN Tower - Size Comparisons

Size Comparisons

The CN Tower is the tallest freestanding structure in the Americas. The only other freestanding structure in the Americas to exceed 500 m (1,640.4 ft) in height is the Willis Tower in Chicago, which stands at 527 m (1,729.0 ft) when measured to its pinnacle. One World Trade Center, currently under construction in New York City, is expected to have a pinnacle height of 1,776 ft (541.3 m), or approximately 12 m (39.4 ft) shorter than the CN Tower. Due to the symbolism of the number 1776 (the year of the signing of the United States Declaration of Independence), the height of One World Trade Center is unlikely to be increased. The Chicago Spire was expected to exceed the height of the CN Tower, but it was cancelled in early 2010.

Between 2010 and 2013, the rank of the CN Tower in the list of the world tallest structures is expected to drop considerably. At least seven structures currently under construction, all of which are scheduled to be completed by 2013, are expected to exceed the CN Tower's height of 553.33 metres (1,815.4 ft) once completed.

Famous quotes containing the words size and/or comparisons:

    Great causes are never tried on their merits; but the cause is reduced to particulars to suit the size of the partizans, and the contention is ever hottest on minor matters.
    Ralph Waldo Emerson (1803–1882)

    Decade after decade, artists came to paint the light of Provincetown, and comparisons were made to the lagoons of Venice and the marshes of Holland, but then the summer ended and most of the painters left, and the long dingy undergarment of the gray New England winter, gray as the spirit of my mood, came down to visit.
    Norman Mailer (b. 1923)
