In order to minimize inconvenience to our customers, we will close the road during the nighttime on weekdays when traffic volume is low, and carry out the work in an intensive and efficient manner.

5. Transfer arrangements due to road closures
通行止めにより高速道路を一旦流出し、通行止め区間を迂回して、再流入して順方向に乗り継がれるお客さまには、ご利用区間に応じて通行料金を調整する「乗継調整」を実施します。(別紙-2【PDF:138KB】参照)
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 road closure is lifted after exiting at an exit IC, the toll will be adjusted even if you re-enter from an IC in the road closure section in the forward direction or from an exit IC.
- Oshu Smart IC is only available for ETC-equipped vehicles.
Precautions regarding transit fare adjustment
- After the road closure is lifted, transfer fares will be adjusted even if you enter from a designated exit interchange.
- If there is an outflow at the IC in the road closure section, or if it is re-inflow after the road closure is lifted, the transfer fare will be adjusted.
- Only vehicles with ETC equipment can use the Oshu Smart IC, Hanamaki PA Smart IC, and Yokote Kita Smart IC.
