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 with cash, etc.

• 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 road closure is lifted after flowing out from the outflow designated IC, the toll will be adjusted even if it is reinflowed from the IC (including the outflow designated IC) in the closed section in the forward direction.

Four. Construction overview

1. Due to the extension of runway B at Narita Airport, it is necessary to create an overpass between the existing Higashi Kanto Expressway and the B runway extension. We are planning to carry out construction work.
   This time, we will carry out construction to remove the existing 2 overpass bridges that will be a hindrance in order to temporarily detour the Higashi Kanto Expressway. Since the work to remove the overpass is carried out on the main line of Higashi Kanto Expressway using a multi-axle truck, it is necessary to implement a road closure. In order to minimize inconvenience to customers, the road will be closed at night on weekdays when there is little traffic. We ask for your understanding and cooperation.

   

2. Along with Ken-O Road (between Daiei JCT and Matsuo-Yokoshiba IC) construction projects, we will carry out the bridge construction work for the main line bridge and ramp bridge that intersect with the Higashi-Kanto Expressway. Since the collective erection work will be done on the main line of Higashi Kanto Expressway using a multi-axle truck, it is necessary to implement a road closure. In order to minimize inconvenience to customers, the road will be closed at night on weekdays when there is little traffic. We ask for your understanding and cooperation.
