Construction summary

Nihonkai-Tohoku Expressway A wire rope is trially installed as a traffic safety measure on a part of the provisional two-lane section (earthwork section) in April this year between Nakajo IC and Arakawa woto IC, but this time the medium small bridge (in the section) Wire rope will be installed on a part of bridge less than 50m long. In addition, in addition to the wire rope installation work in the small and medium bridge part, a wire rope will be installed in the earthwork section (wire rope not installed section) between bridges, and the wire rope section will be extended to strengthen traffic safety measures.
