For the floor slab replacement work, the section of each of the two lanes on the upper and lower lanes will be reduced to one lane each, and will be consolidated on one side to implement two-way traffic restrictions throughout the day. During the first and last few days of the construction period, lane restrictions will be applied to both the upper and lower lanes as a preparatory work for switching lanes.

Four. Construction content

About 44 years have passed since the opening of Matsunokizawa Bridge, which is located between Hiraizumi-Maesawa IC and Mizusawa IC on the Tohoku Expressway. As a result of such factors as deterioration of the concrete deck and rust on the reinforcing bars, it is necessary to carry out drastic anti-aging work.
By replacing the deteriorated existing concrete deck with a new deck, it will be reborn as a safe and comfortable Expressway.
