Rainbow Bridge

Rainbow Bridge links Central Tokyo to the man-made islands of Daiba, and carries a motorway, an ordinary dual carriageway and the Yurikamome unmanned railway system. Though quite why it is "rainbow" is anyone's guess, given that it is not even vaguely semi-circular, nor colourful...nor gender diverse... I suppose it would not have quite the same ring to it if named the "Slightly Curved Central Span Bridge".
