Underground projects for the Nihonbashi section of the Tokyo Metropolitan Expressway are underway. The bridge girder was removed near the abolished Edobashi entrance, and the work of removing piers (pillars) proceeded. The piers that used to be like "stumps" have disappeared, and the area near Edobashi is a paragraph? Of course, this is just the beginning of the business.
Until 2035, difficult construction to pass a new tunnel through a place where there are many bridges and underground buried objects without stopping the traffic that passes 100,000 vehicles a day. The work to remove a huge amount of structures that have been used for a long time will take a long time, and the project will be completed in 2040. I wonder if I was living at that time. You have to be careful about your health until you see the completion.
The progress of construction is announced on the website of Tokyo Metropolitan Expressway Co., Ltd. Let's watch and support you. Infrastructure is a lifeline that supports economic activities and protects the lives of citizens.
