New interchange development project

Last Updated April 4, 2024

Business Overview

 In order to maximize the function of the wide-area disaster prevention base, which is being considered for development in the former Kami-Seya communication facility area, and to improve daily traffic convenience and revitalize the area, this area and the Tomei Expressway We are conducting full-scale studies to develop a new interchange (IC) that is directly connected.

Business effect

(1) Strengthen the functions of wide-area disaster prevention bases in the event of a large-scale disaster
 In the event of a large-scale disaster, the Tomei Expressway, which is the main artery for emergency and rescue activities and transportation of emergency supplies, is directly connected to a wide-area disaster prevention base, and its functions are maximized.
(2) Improvement of wide area access
 By passing through the roads around Kamiseya, which is being developed for the new IC and GREEN x EXPO 2027, access to expressways will be reduced and wide area access will be improved in the western part of the city, including Seya Ward and northern Izumi Ward.
(3) Promotion of the formation of new revitalization bases in suburban areas
 Directly connected to the Tomei Expressway, it attracts the location of core logistics bases that enable efficient domestic logistics utilizing new technologies, and enhances the lives of citizens and revitalizes the city economy by strengthening logistics functions. I will connect it.
