Aqualine
Expressway in Tokyo Bay
We invite you to tour Aqualine Tokyo
Bay, the longest highway under the sea in the world
The
pharaonic engineering work was officially inaugurated on December 18, 1997 with
the aim of joining the Japanese cities of Kawasaki and Kisarazu through a
bridge and an underwater tunnel.
The
imposing passage under the sea, runs through Tokyo, linking the cities of
Kawasaki and Kisarazu.
On
December 18, 1997, Japan once again surprised the entire world by officially
inaugurating Tokyo's Aqualine Bahia, the longest highway under the sea in the
world.
Built
with the main objective of allowing the circulation of
vehicles on a road known as CA, which is made up of a bridge and an underwater
tunnel, the pharaonic civil engineering work crosses Tokyo Bay, uniting the
Japanese cities of Kawasaki and Kisarazu. .
The high volume of ship traffic in Tokyo Bay was the main
reason that led the Japanese government to build approximately the first 10
kilometers of this global engineering giant, starting from the city of
Kawasaki, in the form of an underwater tunnel.
The total length is
almost 15 kilometres, since while the bridge measures 4.4 kilometres, the
tunnel is 9.5 kilometers long, which represents a considerable saving in travel
time between the two points since, in the In case of wanting to make this
displacement by the alternative route, the distance traveled would be 100
kilometers, so, beyond the significant reduction in terms of time spent, it is
also possible to decongest the otherwise crazy traffic in the Japanese capital.
artificial islands
Meanwhile, while the interior diameter is 11.9 meters, the
exterior is 13.9 meters, which gives it the quality of indestructible. At the
junction between the underwater tunnel and the bridge there is an artificial
island called Umihotaru, which was specially equipped with rest areas,
restaurants, shops and has a spectacular viewpoint from which, on clear days,
you can see the best postcards. both from Tokyo Bay and its surroundings as
well as from Mount Fuji and Tsukuba.
In addition, it has another artificial island that is known
worldwide by the name of "Wind Tower" (風の塔 Kaze no
tō) since it was designed to act as a tunnel vent. The construction works of
this true world architectural jewel demanded more than nine years of work and
an investment of 11,200,000 dollars.
With affection,
