3. Construction overview

Due to damage to the pavement, pavement repair work will be carried out at the Tanigawachi Nishi Intersection (tentative name) and Tanigawachi Intersection (tentative name) on Keiyo Road (flat section) heading towards Shinozaki IC on National Route 14. As normal lane restrictions will not allow work to be carried out on the sections where this work will be carried out, it will be necessary to close the intersections in four different patterns to carry out the work.
Therefore, in order to minimize inconvenience to our customers, we will close intersections at night on weekdays when traffic volume is low, and carry out the work in a concentrated and efficient manner. This work is necessary to ensure that customers can use Expressway safely and comfortably, so we ask for your understanding and cooperation.
