The removal of the communication passage was carried out for the parallelization of the Saikyo line home and the Yamanote line home which is being carried out as part of jr Shibuya Station improvement work. Report the risks and solutions for the removal of t6-G single digits across National Highway 246 and the Capital Expressway crossing at the top. There was a concern that the separation between the capital expressway and the Saikyo line down electric pole was only about 200mm, and that there was a possibility of contact to the overhead line and temporary communication passage by the loading of the earthquake etc. at the time of hanging. I was able to finish without trouble.
