Four. Construction content

Approximately 43 years have passed since the opening of the Kuzumarugawa Bridge between Hanamaki IC and Shiwa IC on the Tohoku Expressway As a result of such factors as deterioration of the concrete floor slab and rust on the reinforcing bars, it is necessary to carry out drastic anti-aging work.
By replacing the deteriorated existing concrete floor slab with a new floor slab, it will be reborn as an Expressway
