Boso Hanto - Crossing Tokyo Bay by the Aqualine
-----------------------------------

It took 31 years to study the possibility to build a road connection in the middle of the Tokyo Bay and build the Aqualine, which opened to traffic in December 1997 after 8 years of construction. The total cost reached... 1.44 trillion yens (11 billion dollars)!

from http://www.pref.chiba.jp/syozoku/b_soukei/keikaku/outline/graphics/umihotaru2.gifThe journey by car is fun, and the main interest is the Umi-hotaru island, built like an attraction park with large parking lots, view points, shops and restaurants. This island - 650 meters long - has the shape of a liner. When the weather is clear, you can see from the top of the building as far as Shinjuku, Yokohama and the Fuji-san!

This picture shows a schematic of the tunnel, which shows the 2 lanes where cars are driving. There is a second tunnel of the same size next to it for cars driving in the opposite direction. Each of the tunnels has a diameter of about 14 meters!


The crossing cost for a car of normal size is 3000 yens. The toll fee was higher at the inauguration, but it was later lowered since the traffic was much smaller than expected. The main concept behind this construction was to offer another way around Tokyo, thus lowering the number of cars crossing through the capital. But due to the hefthy fee, few people changed their habit. And this price is expected to increase to 4000 yens in 2008...


Crossing by bus

If you do not have a car, you can still enjoy crossing the bay via the Aqualine. Here is a list of some of the lines using this facility : www.keikyu-bus.co.jp/keikyu-bus/aqua.html
