How to use transit adjustment

<< ETC customers >>

  • Customers using ETC are requested to run the outflow designated IC wirelessly and the re-inflow designated IC wirelessly. (No transit certificate will be 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 for cash, etc. >>

  • Customers who pay by cash, etc. should receive the "passage certificate" at the outflow designated IC, and then get the "passport" at the re-inflow designated IC, and then make the "transfer" at the toll booth that pays the fare first. Please give us your "certificate" and "passport".

《Common to customers such as ETC and cash》

  • 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

Ken-O Road Traffic will be closed at night between Matsuo Yokoshiba IC and Kisarazu Higashi IC for repair work on damaged pavement and repair and inspection of road structures such as continuous tunnels and bridges.
Since the section where this construction is carried out is one lane on one side, and it is not possible to construct under normal lane regulations when carrying out construction, we will close traffic at night on weekdays when traffic is low as much as possible so as not to cause inconvenience to customers, and carry out construction intensively and efficiently. It is necessary construction in order to use Expressway safely and comfortably, so please understand and cooperate.
