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

Since the pavement of the Nagano Expressway Koshoku IC and Koshoku JCT lamps is deteriorating, we will carry out pavement repair work. Since it is not possible to carry out construction under normal lane regulations, it is necessary to close the lamps before starting work. Therefore, in order to avoid inconvenience to customers as much as possible, we will close the lamps on weekday nights when traffic is light and carry out construction intensively and efficiently.
This work is necessary to use Expressway safely and comfortably, so we ask for your understanding and cooperation.
