Around 07:40 hours on October 21,
1994, Seongsu Bridge connecting Seongsu-dong
and Apgujeong-dong of Gangnam-gu, Seoul,
collapsed. The slab (48 m) between the
fifth and the sixth leg of the Bridge
collapsed so 32 people died and 17 people
were injured while they were on the
way to office or school.
Seongsu Bridge is the 11th bridge constructed
over Han River. Its construction was
set about on April 9, 1977 and completed
on October 15, 1979, 2 years and 6 months
later. It is four-lane bridge with 19.4m
width and 1,160.8m length.

Dongah Construction worked on its
construction, spending £Ü11.58 billion.
Unlike the existing bridges oriented
in functions, it employed Gerber Truss
engineering in consideration of beauty.
Through investigation, it was found
that: joints of trusses (steel structures)
supporting the bridge slab were not
welded to the full; the welding thickness,
which should be over 10mm, was only
8mm; and further, connecting pins for
steel bolts were poor.
From April 26, 1995, Hyundai Construction
set about the construction to recover
the bridge with £Ü78 billion, and on
July 3, 1997, 2 years and 8 months later
after the accident happened, passage
of vehicles was commenced again. |
