The Rainbow Bridge is a suspension bridge crossing northern Tokyo Bay between Shibaura Pier and the Odaiba waterfront development in Minato, Tokyo, Japan. Construction of the bridge started in 1987 and it was completed in 1993. The bridge is 798 metres long, with a main span of 580 metres. Officially called the 'Shuto Expressway No. 11 Daiba Route - Port of Tokyo Connector Bridge', the name 'Rainbow Bridge' was decided by the public. Designed to harmonise with the skyline of central Tokyo as seen from Odaiba, the towers supporting the bridge are white in colour. There are also lamps placed on the wires supporting the bridge, which are illuminated in red, white and green in the evening, using solar energy obtained during the day. The Rainbow Bridge can be accessed by foot from Tamachi Station or Shibaura-futō Station on the mainland side.
