NEXCO EAST Ichihara Management Office (Ichihara City, Chiba Prefecture) and the Tokyo Wan Aqua-Line Expressway Management Office (Kisarazu City, Chiba Prefecture) will be implementing a night-time road closure on the C4 Ken-o Expressway (hereinafter referred to as the "Ken-O Road") from Matsuo Yokoshiba Interchange (hereinafter referred to as the "IC") to Kisarazu Higashi IC to carry out pavement repair work, structure inspections, etc.
In addition, the Choshi Link Road (managed by the Chiba Prefectural Road Public Corporation), which connects directly to the Ken-Ken-O Road, will also be closed (entry prohibited) because customers who entered from the Yokoshiba Hikari Interchange will not be able to exit onto the general road from the Matsuo Yokoshiba Interchange.
We apologize for any inconvenience this may cause, and we ask for your understanding and cooperation in allowing yourself plenty of time when heading out.

How to use transit adjustment

ETC customers

  • For customers using ETC, please drive wirelessly at designated outflow ICs, and also wirelessly drive at re-inflow ICs. (Transfer certificates are not issued for ETC vehicles)
  • ETC time zone discount will be applied, considering the transited journey as one.
    Toll charges are adjusted at the time of billing, so they may differ from those displayed at the toll gate.
  • Insert the same ETC card for all journeys and pass through the ETC lane at the tollgate.

Customers such as cash

  • Customers paying with cash, etc. should receive a "transfer certificate" at the outflow designated IC, then take a "transit ticket" at the re-inflow IC, and then take the "transition certificate" at the toll booth where they pay the toll for the first time. Please hand over your ``book'' and ``traffic ticket.''

Common to ETC and cash customers

  • If the suspension of traffic is released after the outflow designated IC is released, the fare will be adjusted even if it is re-introduced from the IC (including the outflow designated IC) in the closed road section in the forward direction.

Four. Construction overview

A night-time road closure will be implemented on Ken-O Road between Matsuo Yokoshiba IC and Kisarazu Higashi IC to carry out repair work on damaged pavement and inspection of structures.
The section where this work will be carried out has only one lane in each direction, and since the work cannot be carried out under normal lane restrictions, in order to minimize inconvenience to customers, we will close the road 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.
