2. Detour

For information on detours to public roads, please see Appendix 1 [PDF: 46KB].

3. Regarding transit adjustments due to suspension of traffic

For customers who exit Expressway due to a road closure, detour around the closed section, then re-enter and transfer in the same direction, we will implement a "transfer adjustment" in which the toll will be adjusted according to the section of the expressway they are using. (See Appendix 2 [PDF: 42KB])

Transfer IC

The transfer ICs are as follows. For details, please see Appendix 2 [PDF: 42KB].

Outflow designation IC	Tohoku Expressway (Out-bound)	Nishinasuno-Shiobara IC, Yaita Kita Smart IC, Yaita IC
Re-inflow IC	Tohoku Expressway (Out-bound)	Kuroiso Itamuro IC, Nasu IC, Nasu Kogen Smart IC, Shirakawa IC

How to use transit adjustment

ETC customers

• For customers using ETC, please drive wirelessly at designated outflow ICs, and also wirelessly drive at re-inflow ICs. (Transfer certificates are not 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 paying with cash, etc. should receive a "transfer certificate" at the outflow designated IC, then take a "transit ticket" at the re-inflow IC, and then take the "transition certificate" at the toll booth where they pay the toll for the first time. Please hand over your ``book'' and ``traffic ticket.''

Common to ETC and cash customers

• 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.
