In 1974, it was succeeded by the Warsaw radio mast as the world's tallest structure. The Warsaw mast collapsed in 1991, again making the KVLY-TV mast the tallest structure in the world until the Burj Khalifa surpassed it in 2008. It became the third tallest when the Tokyo Skytree was completed in 2012, then the fourth tallest when the Shanghai Tower took third place in 2013. It remained the tallest structure in the Western Hemisphere, and the tallest broadcasting mast in the world until the antenna removal in 2019.
Location
The mast is located 3 miles (4.8 km) west of Blanchard, North Dakota, halfway between Fargo and Grand Forks. It became the tallest artificial structure, and the first man-made structure to exceed 2,000 feet (610 m) in height, upon the completion of its construction on August 13, 1963.
Construction
The tower was built by Hamilton Erection Company of York, South Carolina, and Kline Iron and Steel, and required thirty days to complete, at a cost of approximately $500,000[2] (roughly $4.98 million today[3]). Construction was completed August 13, 1963.[4]
