The height between each story was 2.7 m. On 2nd March 1973, some portion of the apartment building collapsed during construction. But other structural engineers said that some level of corrosion was common in old buildings and was unlikely to bring a building down on its own. But its length was not what made the bridge so famous that it continues to fascinate engineers and physics professors to this day. /Font << << A crucial clue is still unknown, Professor Bentz said, and that would probably be found under the debris where the collapse seemed to start..
