Akashi-Kaikyo or Pearl Bridge:
Kobe-Naruto, Japan
The
Akashi-Kaikyo bridge, alternatively known as the Pearl bridge was opened in
Japan on 5th April, 1998; after a period of approximately ten years
from the start of the construction work. This is the longest ever suspension
bridge of the world with a main span of 1,991 meters. The construction of the
bridge involved the participation of more than 100 contractors.
The
Akashi-Kaikyo bridge is a part of the Kobe-Naruto highway and connects the
southern island of Shikoku with the main island of Honshu. The bridge is four
kilometers long and crosses the waterway Akashi Sraits. The waterway connects
the Kobe area of Honshu with Awaji island. The bridge effectively enhanced the commercial
and industrial development of both the connecting regions.
The
total length of the bridge is 3,911 meters and is divided into three spans. The
central span is about 1,991 meters while there are 960 meters streached side
spans. The roadway surface of the bridge is built on the top of a 14 meters
deep and 35.5 meters wide truss girder system. According to the reports by the
Honshu-Shikoku Bridge Authority, about 1.42 million cubic meters of concrete
and 181,400 metric tons of steel were used in the total construction of the suspension
bridge.
