The Construction of Rainbow Bridge 5: Completion

1993, before opening
1993, the opening of the Rainbow Bridge

Six and a half years after construction began, the Rainbow Bridge finally connected with Route 11 Daiba Line. Its inauguration day on August 26, 1993 was unfortunately rainy, but it still had a grand debut on Tokyo Harbor[2]. The Inner Circular Route and the Bay Shore Route were also connected from north to south in addition to the one old route, easing the traffic congestion near Hakozaki Junction, and smoothing the connection of the Tokyo Bay Area with the new Haneda Airport and the inner city. Furthermore, the choice of routes to the Tokyo Waterfront Sub-center increased, raising the profile of the area.

  1. From this series of narratives, it appears that the Rainbow Bridge holds significance -both as the pivot of different forms of transport and as the icon of urban development, as you mentioned in the first narrative that it is ‘the foundation for the future success of the 7th sub-centre in Tokyo”. It is, therefore, not hard to see why the public has endeared the infrastructure as the ‘Rainbow Bridge’.

    Whereas you organised this series according to the bridge’s construction process, I’m more interested in public proposals, debates and lastly perception towards the project upon completion, since you delineated the Bridge’s great social importance. What were some of the suggestions made before construction, and why were they deemed as less ideal? How did the building authorities navigate among all the different proposals?

  2. To Yanheng’s credit, the focus on a bridge and infrastructure question in an urban expansion plan is quite revealing. Going deeper will definitely expose how the operation of Odaiba can be successful, whether it’s the train line or the highway that bring about greater connectivity to the existing city. To plan Odaiba between Haneda and downtown Tokyo may also be a strategic decision.

    I tend to agree with Gladys that a review of the public’s reaction, other planning proposals or even failed proposals surrounding this infrastructure project would also teach us more about the eventual success or challenges of this particular bridge and site. However, your reliance on the three sources, especially the two sources from the governmental agencies themselves would unlikely expose the real difficult issues or even contradictions suffered during the entirety of the project.
