Regarding connection adjustments due to road closures

For passengers who leave the Expressway once due to a nighttime closure, bypass the closed section, re-enter and transfer in the forward direction, we will make a "transit adjustment" to adjust the toll according to the section used .

How to use transit adjustment

≪ETC customers≫

  • Customers using ETC are requested to run the outflow IC wirelessly and the re-inflow 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 such as cash≫

  • Customers who pay in cash, etc. should receive the "passage certificate" at the outflow IC, then collect the passport at the re-inflow IC, and then the "transfer certificate" at the toll gate where the fee is paid first. Please give a pass ticket.

≪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.
