How to use transit adjustment

ETC customers

  • Customers using ETC are requested to run the outflow IC wirelessly and the re-inflow IC wirelessly. (“Transit certificate” will not 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 such as cash

  • 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.

Common to ETC and cash customers

  • If the road closure is lifted after exiting at the exit IC, the toll will be adjusted even if you re-enter from an IC in the closed section in the forward direction (including the exit IC).

Four. Construction overview

Repair of damaged road surfaces, structural inspections, and road cleaning work will be carried out on the Nitto Highway, both upper and lower, from the Niigata Airport Interchange to the Arakawa-Tainai Interchange. 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 construction work intensively and efficiently. We ask for your understanding and cooperation as this work is necessary for the safe and comfortable use of Expressway.

Five. How to obtain traffic information

(1) Guidance by distribution / posting

  • Notice signs, posters and leaflets will be posted at toll booths and rest facilities nearby.

(2) Road traffic information that can be obtained before going out

(3) Road traffic information available while using the Expressway

  • Road information board
  • Highway radio (AM1620kHz)
    The section where the highway radio is broadcasting is indicated by the sign on Expressway.
  • Highway Information Terminal
    Wide-area road traffic information is notified on the monitor screen installed in SA / PA.
  • VICS
    Road traffic information can be obtained from devices such as VICS-compatible car navigation systems.

Regarding the closure of one lane section of Nihonkai-Tohoku Expressway

Generally, on Expressway with two lanes in each direction, lane restrictions are implemented as necessary to repair damaged road surfaces and inspect various facilities. Nihonkai-Tohoku Expressway is a one-lane road, so road closures are essential for construction and inspections. For this reason, Nihonkai-Tohoku Expressway closes twice a year, in spring and autumn, excluding Golden Week and the summer peak season, to ensure safety and security on Expressway.
We apologize for any inconvenience this may cause our customers, and we appreciate your understanding and cooperation.
