- Construction of the Tohoku Expressway Asahionnami Section is underway, with plans to build 21 large tunnels and 26 bridges.
- Excavation work on the 9th tunnel is expected to be completed, and full-scale construction is scheduled to begin in 2024.
- Upon completion of this section, it is expected to improve transportation convenience in the Sea of Japan coastal region, and have a positive impact on industrial revitalization and attracting tourists.
The Tohoku Expressway stretches long north-south along the coast of the Sea of Japan. Among them, construction is underway on the "Asahionnami Section" located in the border area of Niigata Prefecture and Yamagata Prefecture. A significant portion of the 40.8km section traverses mountain ranges, necessitating large-scale tunnel construction.
Around May 20th, the excavation work for Tunnel No. 9 (tentative name) on the Niigata Prefecture side is scheduled for completion. The completion of this tunnel is expected to trigger the completion of other tunnels in a chain reaction. Currently, three tunnels, No. 1, No. 4, and Daiamaten (all tentative names), have already been completed, and excavation work is in progress for five tunnels: No. 2, No. 9, No. 11, Nogokukan, and Soamaten No. 1 (all tentative names).
A total of 21 large-scale tunnels are planned for this entire Asahionnami section. This is due to the geographical characteristics of this region, which has many mountainous areas. The total length of the tunnels within the section exceeds 20km, giving an idea of its immense scale.
In addition to tunnel construction, construction of 26 bridges is also progressing steadily. However, only two have been completed so far. In 2024, full-scale construction is expected to commence, including land acquisition, improvement work, tunnel construction, and bridge substructure construction.
The completion of this section is expected to significantly improve transportation convenience in the Sea of Japan coastal area. The construction of a new expressway network in this area, which currently relies on National Route 7, is expected to have positive impacts, such as industrial revitalization and tourist attraction.
However, since a significant portion of the construction section has yet to even begin, it is difficult to estimate the exact opening date. Nevertheless, we hope that construction of this section will be completed as soon as possible, especially to alleviate chronic traffic congestion along National Route 7 and minimize damage caused by heavy snowfall and snowstorms in winter.
