3 Outline of open section
Between the Minamisoma IC and the Soma IC, due to the effects of the Great East Japan Earthquake, construction was temporarily suspended for about two months after the earthquake, and almost all the lines were restored to the earthquake, and it was extremely difficult to secure personnel and procure construction materials and equipment. However, it is expected that it will be opened this time and will serve as the basis for the restoration and reconstruction of Fukushima Prefecture Hamadori.

Location map
Features of the open section
Road standard/road structure
- With the provisional 2-lane construction of Class 1 Class 2 (design speed 100km/h), we have set up a 4-lane section that allows overtaking at two locations.
- It is located a few kilometers inland from the Pacific coast, and is mainly composed of cut soil. Since it is higher inland than National Highway 6, it is a road that is resistant to disasters such as tsunami.
Damage situation of the Great East Japan Earthquake
- The Great East Japan Earthquake caused various damages at many locations. In particular, where the cut slope in the Tsubota area of Soma City collapsed, we acquired an additional site and recut the slope with a gentle slope.
Measures to stabilize the cut slope
- The slope of the Abukuma Mountain side slope is inclined toward the Pacific Ocean side, and since the slope is a terrain that is likely to collapse, we are implementing measures to stabilize the slope by using ground anchors and sprayed frame work.
Current status of the open section
Improvement effect of open section
Travel time is reduced.
- The travel time between Minamisoma City Hall and Soma City Hall will be reduced by about 13 minutes (about 33%).
Secure the mutual complementing function of National Highway No. 6.
- If National Route 6 cannot pass, it will serve as an alternative road function.
It functions as an emergency evacuation road and a road for reconstruction support, and helps reduce congestion on surrounding roads.
- It functions as an emergency evacuation road.
- It functions as a route for material transportation and human movement during the earthquake reconstruction.
