2010年的梅本奈奈子设计工作室与清华大学、东京大学联合主持,其大背景为1960年丹下健三的东京湾规划,一种对无足够成长空间的密集城市的过度拥挤和担忧的回应。已建的东京湾横断道路虽然大大缩短了从千叶到东京的交通时间,然而其高额费用,使它未能如期分流大部分通过东京市中心的交通。对于此基础设施未充分利用的情况,扩大潜在的巨型结构的时机已经成熟。 The 2010 Meibanai Nai sub-design studio co-chaired with Tsinghua University and the University of Tokyo, whose background was the Tokyo Bay Project of Kenzo Tange in 1960, a response to overcrowding and concerns about dense cities without enough room for growth. Although the crossroads of Tokyo Bay have been built, the traffic time from Chiba to Tokyo has been greatly shortened, but its high cost has prevented it from diverting most of the traffic passing downtown Tokyo as scheduled. The time has come to expand the potential mega-structures for underutilized infrastructure.
