Four. Construction content

Approximately 48 years have passed since the opening of the No. 1 Kumatogawa Bridge, which is located between the Yabuki IC and Sukagawa IC on the Tohoku Expressway Due to the salt content of the concrete floor slab and rust on the reinforcing bars, it is necessary to carry out drastic anti-aging work.
