NEXCO EAST Misato Management Office (Misato Prefecture) will be closing the ramps at the interchange (hereinafter referred to as "IC") on the C3 Gaikan Expressway (hereinafter referred to as "Outer Ring Expressway") to carry out pavement repair 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.

1. 1. Ramp closure location and date and time

• 各路線に付しているC3の表示は、高速道路等の路線番号（ナンバリング）を示しています。

2. Construction overview

Due to damage to the road surface at each interchange on the Outer Ring Road, pavement repair work will be carried out.
Since construction work cannot be carried out under normal lane restrictions, it is necessary to close the ramps to carry out the work. Therefore, in order to minimize inconvenience to customers, we will close the ramps at night on weekdays when traffic volume is low, and carry out the work 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.
