[Tokyo Wan Aqua-Line’s construction]
The Tokyo Wan Aqua-Line Expressway consists of two-10km long tunnels (Aqua Tunnel) under Kawasaki waters and a 5 km long bridge(Aqua Bridge) over Chiba waters with two artificial island in between.
Japan’s first marine rest area “Umihotaru” is an artificial island constructed to shift the expressway from the tunnels to the bridge.
There is also a tunnel ventilation tower callded “Kazenotou (Tower of Wind),” on the artificial island in the mid-section of the undersea tunnel and a pyramid shaped Ukishima Ventilation Station near the tunnel entrance on the Kawasaki side.
