100 Years

Conn.
A 100-ft. section of a Connecticut Turnpike bridge collapsed
after one of the pins used in its construction had been sheared.
Deaths: 3 
September 11, 1916: Quebec Bridge,

Due to a design flaw the actual weight of the bridge was
heavier than its carrying capacity, which caused it to collapse twice, first in

Dec. 15, 1967: Silver Bridge, connecting Point

July 17, 1981: Hyatt Regency skywalks, Kansas
City
Two suspended walkways were crowded with people, some who were
dancing. Architects theorized after the collapse that vibrations by the dancers
might have contributed to the structural breakdown, as did the sheer weight of
the crowd.
Deaths:
114
October 21, 1994, Songsu bridge, Seoul, South
Korea
A central section of the structure sheared off during the
morning rush hour and plunged into the Han river. It was determined that the
collapse was the result of the combination of a mistake in maintenance and
defective designs and construction work.
Deaths: 31
January 4, 1999: Rainbow Bridge, Qijiang county,
China
Investigations into the collapse showed that the steel used in
construction was of inferior quality and that the accident resulted from
official dereliction of duty by several government officials, one of whom was
sentenced to death.
Deaths: 49
