Because dropping a heavy tool or even a bolt from a high structure in a busy urban area could pose a serious danger to people below, the builder of the now nearly 400-meter-high Tokyo Sky Tree in Sumida Ward, Tokyo, is taking extraordinary precautions.
Tokyo Sky Tree, which will reach 634 meters when completed, is now 398 meters high and likely to surpass 400 meters by the end of July. In constructing the world’s highest self-standing radio wave transmission tower, workers are doing their jobs at unprecedented heights.
The tower is being built near Narihirabashi Station on the Tobu Isezaki Line in a residential area where the station platform, rails and houses are concentrated.
Below the tower, trains come and go, and nearby residents walk on roads. (Yomiuri)
