Tokyo Bay Bridges: Rainbow Bridge (2)

At 570 m, the Rainbow Bridge is very short for a suspension structure. The Tatara (cable-stayed) Bridge is 890 m. The Lupu (arch) Bridge is 550 m. Perhaps the engineers felt obligated to build a suspension bridge because the nearby long-span structures are cable-stayed bridges.

The Rainbow Bridge spans between Shibauru Wharf and the Daiba District. Considering the span length is so short, it's surprising that the east tower sits in Tokyo Bay. Maybe there was no place to put the tower on land, since the bridge swings to the north from the eastern tower before reaching Daiba.
