The Tunnels
of Namsan
 There
are three tunnels which pass through in the Namsan, and we call them
First-Ho, Second-Ho, Third-Ho according to the time they were built.
First-Ho, whose length is 1,530m, width is 9.0m and lane is two, is
connected from Phil-dong in Jung-Gu to Hannam-Dong in Yongsan-Gu.
On the September In 1975, It was repaired for the first time because
it had some problems such as severe leaking water and unstable system
which manage air-condition in the ternel after completement of tunnel
on August in the 1970. Second-Ho, which is connected between Itewan-Dong
in Yongsan-Gu and Jangchung-Dong in Jung-Gu, was built on December
4th,1970. Its length is 1,620m, width is 7.2mand lane is two. Its
vetical side wall looks like the shape of semi-sphere and also the
depth of lining for waterless is 500mm,It is thicker than First ternel.
It was renovated in the wall which was renewed with tiles, in light
and in the equipment of fire-work.Third-Ho ,which is connected between
Itewan-Dong in Yongsan-Gu and Hwehyung-dong in Jung-Gu, is 1,280m
long. It was built in March 31st ,1978 after it started to be built
in May 14th 1976. Its side wall is like Second-Ho tunnel and lining
depth for waterless is 600mm.It also was renewed in light and the
equipment of fire-work when Second and Third was renovated. Third-Ho
has very similar route to Second-Ho tunnel has since It is next to
Scond-Ho tunnel. These three tunnel, which are connect between South
of Hangang (Hanriver) what we call Kangnam and North of Hangang what
we call Kangbuk, helped to save time to go from Kangnam to the down-town
in the Kangbuk, it took half an hour to get to each place and to move
population in Kanbuk. They also helped to drive through down town
from the freeway of the Kangnam and the highway of the Kyungbu. However,
Traffic jam is getting hard because the width of the roads in the
tunnels is narrower than the freeway of Kangnam which is connected
with These tunnel. It is adopted the even oneway system especially
in the peak time. These tunnels are going to be renovated because
there are still problems such as leaking water, management of air-condition
and lightening system in the front tunnel. |
