4 Regarding connection adjustment due to suspension of traffic

By night-time closures, we will perform "transit adjustment" to adjust the toll depending on the section used, for customers who once flow out of the Expressway and bypass the closed section and transfer again in the same direction. ( Attachment-1 [PDF: 111KB] reference)

How to use transit adjustment

[Customers of ETC]
  • Please use the same ETC card for all the processes of the toll gate that once leaks, the toll gate when transferring and the final toll gate after connecting, and run with ETC wireless communication at both the entrance and exit. (For ETC vehicles, no "transfer certificate" will be issued.)
  • ETC time zone discount will be applied, considering the transited journey as one. The price display shows the amount before the price adjustment. The amount will be the amount after adjusting the fee when billing from a credit card company, etc. at a later date.
[Customers for cash, etc.]
  • Customers who pay by cash, etc. should receive the "passenger certificate" at the outflow IC and then collect the "passport" at the re-inflow IC. Please give "and" a pass ticket.
