NEXCO EAST Kazo Management Office (Tohoku Expressway City, Saitama Prefecture) will be closing ramps at night to carry out congestion prevention work at Kawaguchi Junction (hereinafter referred to as "JCT") on the E4 Tohoku Expressway Expressway (hereinafter referred to as "Ken-O Road") and Kuki Shiraoka JCT on the C4 Ken-o Expressway (hereinafter referred to as "Ken-O 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.

1. Closed location and date and time

• The designations such as E4 and C4 attached to each route indicate the route numbers (numbering) of Expressway, etc.

2. Construction overview

Tohoku Expressway　Traffic congestion countermeasure work will be implemented on the ramps from Kawaguchi JCT to the outer ring road and from Ken-O Road Kuki Shiraoka JCT to Tohoku Expressway. As shown in the diagram below, colored pavement will be paved before the turnouts to facilitate smoother travel.
Since the construction work cannot be carried out with the normal lane restrictions, it is necessary to close the ramp for the work. Therefore, in order to minimize inconvenience to customers, the ramp will be closed during the nighttime on weekdays when traffic volume is low, so that the work can be carried out in an intensive and efficient manner. We ask for your understanding and cooperation as this work is necessary for the safe and comfortable use of Expressway.

3. Detour

Please refer to Document 1 [PDF: 375KB] and Document 2 [PDF: 448KB] for information on detours.

4. Transfer arrangements due to the closure

Regarding "transfer adjustments," which adjust tolls according to the section used when vehicles exit Expressway due to a closure, detour around the closed section, and then re-enter and transfer, 1) transfer adjustments will not be implemented for the closure of Kawaguchi JCT Tohoku Expressway. 2) transfer adjustments will be implemented for the closure of Kuki Shiraoka JCT Ken-O Road. (See Document 2 [PDF: 448KB])

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.''
