5 Regarding transfer fare adjustment due to suspension of traffic

For passengers who leave the Expressway once due to a nighttime suspension of traffic and bypass the suspension of traffic and transfer to the same direction again, we will make a "transit adjustment" to adjust the toll according to the segment used. ( Attachment-2 [PDF: 413KB] reference)

How to use transit fare adjustment

<ETC customers>
  • Customers using ETC are requested to run the outflow IC wirelessly and the re-inflow IC wirelessly. (For ETC vehicles, no "transfer certificate" will be issued.)
  • 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.
<Customers such as cash>
  • Customers who pay in cash, etc. should receive the "transfer certificate" at the outflow IC and then take the "passport" at the re-inflow IC. Toll booth to pay first Please hand over the "transfer certificate" and "passport".

Precautions regarding transit fare adjustment

After cancellation of the suspension of traffic, the transfer fare will be adjusted even if the traffic is immediately reintroduced from the outflow IC.
