2 What is Aqualine Expedition

"How did you build bridges and tunnels in the sea? ], "How thick is the wall of an undersea tunnel?" , "If a traffic accident or fire occurs in the undersea tunnel, where will you escape?" "...

The Tokyo Tokyo Wan Aqua-Line Expressway, which crosses Tokyo Bay with a bridge and a submarine tunnel, has many construction techniques and safety measures that are not generally known. The aqualine expedition will explore the backyard of the Expressway and get closer to the true image of the unknown aqualine.

In addition, there are many things that you cannot normally experience, such as an inside tour of the vessels owned by the Japan Maritime Self-Defense Force and the Japan Coast Guard, and a test drive of a "lift truck" with a panoramic view of Tokyo Bay.

The Aqualine Expedition will be held as part of the "2017 Summer Festival in Umihotaru" held on Thursday, August 3. Details of "2017 Summer Festival in Umihotaru" will be announced later.
