NEXCO EAST Ichihara Management Office (Ichihara City, Chiba Prefecture) will be closing the ramp at Chiba Higashi Junction (hereinafter referred to as the "JCT"), where Chiba-Togane Road In-bound lanes merge into Keiyo Road Out-bound lanes, in order to carry out antenna installation work.
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: 192KB])

Transfer IC

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.''

Four. Construction overview

Antenna installation work will be carried out at Keiyo Road Chiba Higashi JCT. As the work area is a single lane, normal lane restrictions will not allow the work to be carried out, and so the ramps at Chiba Higashi JCT must be closed to carry out the work. Therefore, in order to minimize inconvenience to customers, the ramps will be closed at night on weekdays when traffic volume is low, and the work will be carried out in a concentrated and efficient manner. This work is necessary to ensure that customers can use Expressway safely and comfortably, so we ask for your understanding and cooperation.

Five. How to obtain traffic information
