2. Work summary

At the Keiyo JCT between the Matsudo IC and Ichikawa Minami IC on the Gaikan Expressway, we will conduct detailed inspections of ETC antennas and mounting struts.
The section where this work is carried out is one lane, and since it is not possible to work with normal lane regulations when carrying out inspections, it is necessary to close the ramp and work. Therefore, in order to cause as little inconvenience to customers as possible, we close the lamps on weeknights when there is little traffic and carry out the work intensively and efficiently. This work is necessary for you to use the Expressway safely and comfortably, so we ask for your understanding and cooperation.
