In the floor slab replacement work, we will reduce the section of each two lanes of up and down lines to one lane and consolidate it on one side to enforce face-to-face traffic all day. For the first few days at the beginning and end of the construction period, both the upper and lower lanes will be regulated all day as preparation work to switch lanes. *About the construction regulation step diagram Attachment [PDF:166KB]Please refer to.

About 40 years have passed since the opening of the Omorigawa Bridge and Matsuzukagawa Bridge between the Tohoku Expressway Nihonmatsu IC and Fukushima Iizaka IC (upper and lower lines). Since the salt content of the anti-freezing agent sprayed on causes the deterioration of concrete floor slabs and rust on the reinforcing bars, it is necessary to implement drastic measures against deterioration.

By replacing the deteriorated existing concrete slab with a new slab, it will be reborn as an Expressway that can be used safely and comfortably.

By adopting a precast PC floor slab, the construction period is shortened compared to usual, and the regulation period is shortened to the maximum.
* Precast is a product manufactured in advance at a factory.
