Thank you for your continued understanding and cooperation in the Tokyo Outer Ring Road Project.
In the vicinity of Higashitsutsujigaoka 2-chome, Chofu City, depressions in the ground surface and cavities in the ground have been confirmed, causing concern and inconvenience to everyone living along the outer ring road.
Based on the "Tokyo Outer Ring Tunnel Construction Review Committee Expert Committee Report" published in March 1991, the area where the ground may be loosened is set as the planned ground repair range, and the inside of the tunnel We have been conducting the survey since then, but we are pleased to inform you that the survey has been completed and we have identified the range that requires measures such as repairs.
The results of the underground survey and the scope of ground repair are confirmed in advance with each member of the committee.
Please check here [PDF: 2.8MB] for the results of the underground survey and the scope of ground repair.
Currently, we are studying the construction method of ground repair work, etc., while consulting with those in the ground repair range about temporary relocation or purchase by the business operator.
In the future, based on these examinations, we will explain the ground repair work to the local residents again.
