Recent Developments in Bridge Design in Japan

There can be no doubt that Japan is amongst the world leaders in bridge design and construction. This is true in terms of number of bridges built, spans achieved to date, and technical knowledge. By the end of the century Japan will hold the world record for both suspended and cable-stayed spans (the Akaishi Bridge at 1990m and the Tatara Bridge at 890m, respectively). It has been estimated that over one-third of all the cable-stay bridges in the world are in Japan. It is also likely that, with a well-developed hightech engineering base, a still-powerful economy and a natural geography which still contains numerous as-yet uncrossed straits and valleys, Japan’s eminence in this sphere is likely to remain strong for the foreseeable future. This paper aims to outline some of the reasons behind this development and in particular to highlight current trends and projects which illustrate the state of Japan’s bridge-building industry. M.M.
