Ring Route 3 (Gumizawa area)

Last update date April 1, 2024

　Ring Route 3 (Gumizawa area) is a district that underpasses National Route 1 and includes a lamp section connecting to National Route 1 up line, and has started business since 1998. As the city planning change of the lamp section was announced on December 25, 2019, we will conduct design, survey surveys, etc. for early service start and promote land acquisition.
　In fiscal 2023, in addition to land acquisition, we examined the design of the underpass construction on National Highway No. 1 on the Totsukamachi side. In fiscal 2024, we will proceed with the construction of towns and land acquisition of functional restoration roads in the district, aiming to order the construction of the underpass itself, and will continue to consider design.
