2. Detour

Please refer to Attachment-1 [PDF: 663KB] for detours.
Due to the detour, the required time will be longer, so please leave with plenty of time.

3. Regarding transit fare adjustment due to road closures

Passengers who temporarily run out of the expressway due to nighttime Expressway closures, detour around the closed section, and transfer in the same direction again will have a "transit charge adjustment" that adjusts the toll according to the section used.
(Refer to Attachment-2 [PDF: 194KB])

Transfer designated IC

How to use transit adjustment

ETC customers

• Customers using ETC are requested to run the outflow designated IC wirelessly and the re-inflow designated IC wirelessly. (No transit certificate will 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 "passage certificate" at the outflow designated IC, and then get the "passport" at the re-inflow designated IC, and then make the "transfer" at the toll booth that pays the fare first. Please give us your "certificate" and "passport".

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.

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.

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

In general, on Expressway with two lanes on each side, lane regulations are implemented as appropriate for repairing damaged road surfaces and inspecting various facilities. Since the Nihonkai-Tohoku Expressway is a one-lane road (two-way traffic section), road closures are essential for construction and inspection. For this reason, Nihonkai-Tohoku Expressway is closed twice a year, in spring and autumn, excluding the Golden Week period and the summer congestion period, to ensure the safety and security of Expressway.
We apologize for the inconvenience and ask for your understanding and cooperation.
