East Nippon Expressway Co., Ltd.

NEXCO EAST Saitama Construction Office (Saitama City, Kan-Etsu Expressway Prefecture) is installing additional lanes as a measure to reduce congestion on both the E17 Kan-Etsu Expressway (hereinafter referred to as the "Kan'etsu Expressway") between Tsurugashima Junction (hereinafter referred to as the "JCT") and Higashimatsuyama Interchange (hereinafter referred to as the "IC") in both directions, and will be implementing night-time road closures to erect an overpass that intersects with Kan-Etsu Expressway Expressway.
We apologize for any inconvenience this may cause, and we ask for your understanding and cooperation in allowing yourself plenty of time when heading out.

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 forward direction, a "transfer adjustment" will be implemented in which the toll fee will be adjusted according to the section used. (See Appendix 2 [PDF: 106KB])

Transfer IC

(※Miyoshi Smart IC and Sakado IC are limited to ETC vehicles.)

How to use transit adjustment

ETC customers

  • Customers using ETC should use wireless LAN to drive through the designated exit IC and also through the designated re-enter IC. (ETC vehicles will not be issued a "Transfer Certificate.")
  • 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.

Four. Construction overview

As an effort to combat congestion, we are currently installing additional lanes, but as the new lanes will interfere with the overpass that crosses Kan-Etsu Expressway, they will need to be removed and a new one installed. This road closure will be used to erect the overpass. A multi-axle trolley will be used for the erection work, and as this will block the driving and passing lanes, a road closure is necessary.
In order to minimize inconvenience to our customers, the road will be closed during the evening on weekdays when traffic volume is low. Thank you for your understanding and cooperation.
