Improvement effect by opening the Tokyo Outer Ring Road (Misato Minami IC-Takaya JCT)
Transportation between Saitama and Chiba (Tohoku Expressway Expressway east Kanto Expressway) was via the city center (capital expressway), but on the June 2, 2018 outer ring road (Misato Minami IC-Takaya JCT) With the opening, about 80% of the traffic has been converted to the outer ring road. Also, due to the opening of the outer ring road and the conversion of four lanes such as the Horikiri JCT to Kosuge JCT, the traffic congestion loss time at the Tokyo Metropolitan Expressway inside the central ring (including the central ring) has been reduced by about 30%.

Conservation of rare plants
Rare plants were confirmed in the areas where the terrain was altered, but since the period of protection was before germination, the soil containing seeds was collected, and after the germination and growth at our group facilities, the environment was similar. I transplanted to the place to do.
To reduce the risk of extinction, we collected the seeds that were raised and stored them at the Shinjuku Gyoen Management Office of the Ministry of the Environment.
Conservation of small animals
Since the planned route will be set up in an area where small animals such as reptiles and amphibians inhabit, we set up a sloping ramp in the waterway to secure a moving route.
