By 1973 the length of the Metropolitan began to be put into place. The rapid motorization of Japan from the Expressway exceeded 100 km. Meanwhile, late 1950s onward brought enormous awareness of pollution issues was rising congestion to the streets of central Tokyo. among the Japanese people, as evidenced This concern, together with the selection by the passage of the Environmental of Tokyo as the venue for the 1964 Olympics, Pollution Prevention Act and discussion of spurred the construction of the Metropolitan pollution in the Diet. Expressway at a breakneck pace. In December 1962, the first expressway, covering 45 km between Kyobashi and Shibaura, opened to traffic. This was followed by another 33 km section by the start of the 1964 Tokyo Olympics, enabling large numbers of spectators and athletes to use it to travel from Haneda Airport to the National Stadium and Olympic Village. Toward a Sustainable Society (Late 2000s to present) New Measures for Harmony Metropolitan Expressway carries out painstaking inspection and appropriate repairs on a with Regional Communities daily basis. We are constantly upgrading (Late 1990s to late 2000s) our expressways to ensure their long-term soundness. In consideration of roadside environments, Network Expansion By upgrading infrastructure, we are enhancing Metropolitan Expressway moved ahead with the efficiency of maintenance while contributing and Cityscape the construction of tunnels for new routes. to reduction of environmental impact. (Late 1980s to late 1990s) Responding to general public demand for a deeper relationship with the environment, By the end of the 1980s the Metropolitan the Company undertook new environmental Expressway had been extended to over 200 measures toward harmony with regional km. The network had continued to expand, communities, such as preserving biodiversity with the opening to traffic of the Bayshore and reducing energy consumption. Route and Saitama Omiya Route. At the same time, concern was growing about the effect of expressways on the cityscape. Metropolitan Expressway took steps to improve the cityscape, overhauling the designs of major bridges and beautifying viaducts on routes in operation. Our Stance on Environmental Action We strive to contribute to a sustainable society while preserving regional and roadside environments, to achieve a better environment and harmony with regional communities. To organize its stance on environmental measures SDGs in concrete terms, Metropolitan Expressway establishes four pillars of environmental action, Adopted at a summit of the United Nations in September 2015 with the supported by a common platform of environmental management. approval of 193 member nations, the Sustainable Development Goals (SDGs) Stance on Environmental Action consist of 17 goals for the future of the environment, society and economies. Declaring that the world’s countries were committed to efforts beyond their individual interests, the stated aim of the SDGs is to make the world of the future a better place for all.
