New York (CNN) -- Construction crews at the 16-acre World Trade Center site
will raise the final two sections of a 408-foot spire to the top of One
World Trade Center on Monday morning, making the building the tallest in the
Western Hemisphere, according to the site's management.
A stainless steel beacon weighing almost six tons will be the final piece
put in place to give the building an iconic height of 1,776 feet, according
to a news release from the Port Authority of New York and New Jersey.
Once the architectural structure is complete, it will be comprised of 18
separate sections of steel and three communication rings. The first -- and
heaviest -- steel section was installed in January, weighing more than 67
tons, the news release said.
Port Authority Assistant Director of Media Anthony Hayes said the original
design included a radome -- short for radar dome --but that was rejected
because of anticipated servicing and maintenance difficulties. The radome
would not have impacted the height, but would have provided an additional
design element, which ultimately proved impractical, Hayes told CNN.
The spire will serve a television broadcast facility housed in One World
Trade Center, the press release said.
While under construction, One World Trade Center became New York City's
tallest building a year ago, standing 1,271 feet above street-level. The
building then was 21 feet higher than the Empire State Building's
observation deck. |

雖然歐洲及非洲的西部在西經，但為避免被本初子午線分割，所以西半球及東半球的分
界線是西經20°及東經160°。
