4 Construction details

About 40 years have passed since the opening of the Sansakogawa Bridge between Tsukidate IC and Wakayanagi Kanari IC on the Tohoku Expressway cracks caused by repeated wheel loading due to the increase in size of the vehicle, salt content of the antifreezing agent sprayed during the winter As a result, concrete floor slabs have deteriorated and reinforcing bars have rusted, so 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.

Construction overview

6 Efforts to minimize inconvenience to customers due to construction

Use of precast products for shortening the construction period and improving quality

By adopting precast products for floor slabs and wall balustrades, we have shortened the construction period compared to usual and shortened the regulation period to the maximum. * Precast is a product manufactured in advance at a factory.
