Completion will be in 10 years The opening of the Tokyo section of the outer ring road is in sight There is movement in the construction section of the cave-in accident

In October last year, a ground subsidence accident occurred directly above the shield tunnel excavation route in the Tokyo section of the outer ring road. Loosening of the ground was discovered in the section of

It was recognized that they were due to tunnel excavation work, and the operator, NEXCO EAST, promised to stop the southbound tunnel construction from the Tomei side that caused the cave-in accident for two years. All other shield machines have also stopped drilling, and construction has stopped almost entirely. Will it be completed in 10 years?

It's been about a year since the discussion with the local residents

, but what is the current situation? On September 14, there was a press release from construction companies such as the Kanto Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism. Tunnel excavation has stopped as usual, but discussions with residents living near the accident site seem to be progressing more smoothly than expected.

According to the announcement, about 250 of the approximately 1,000 households in the area subject to compensation for collapse accidents received consultations for house surveys, of which 245 surveys were completed and 170 repairs were completed. It is already underway or has been completed. In addition, there is also the “number of households that are responding to consultations regarding compensation for damages other than those mentioned above,” which is 45 cases. It is presumed that mental stress and the like are included.

Personally, when the collapse accident occurred, I was worried that the construction could not be resumed. In May of this year, when the contents of the residents' briefing were announced and the promise was made to restore the ground looseness caused by the construction to its original state, he said, ``Since it is impossible to strictly restore the status quo, it may not be possible to resume construction.'' I was hopeless, but now I see hope. Will it be completed in 10 years? Opening of the Tokyo section of the outer ring road in sight Movement in the construction section of the cave-in accident

Completion may take 10 years

The specific exchanges between the business operator and the residents are not disclosed, but 245 out of 250 cases "Investigation completed" is surprisingly smooth. The southbound tunnel in question will remain unexcavated for another year, after which it may be able to resume. After the resumption of construction work, excavation work will be carried out with much more caution than before in order to prevent a recurrence of the accident. In other words, the progress of the construction will be significantly delayed, but there is no public opinion to stop the construction of the outer ring road! . It's just a guess, but it may be completed in about 10 years.

Originally, the goal was to open the Tokyo section of the outer ring road by the 2020 Tokyo Olympics and Paralympics. If it were to open 10 years later, it would be about 11 years later than that, but it is not unusual for the expressway opening target to be delayed by about 10 years. I'll have to wait patiently.
