Tokyo Gate Bridge
Tokyo Gate Bridge (aka “Dinosaur Bridge”) is a 2,618-meter long bridge completed in 2012. It crossesTokyo Bay from Wakasu Island to Chuo Bohatei (“Central Breakwater”). Interestingly, both sites are artificial islands made out of trash, although only Chuo Bohatei is still active and serves as the final disposal site of waste from all of Tokyo. The bridge then leads to a tunnel emerging in Jonanjima Seaside Park, near Haneda Airport and the Port of Tokyo.
It is possible to walk on the bridge, starting from a tower in Wakasu Park (map). However, the tower on the other side is closed, so you have to double back. Access to the bridge is free but it closes at 5pm.
