2. Construction overview

Due to damage to signs at the Kazo IC and Iwatsuki IC on Tohoku Expressway, construction work will be carried out to replace signs. In addition, construction work will be carried out to update the aging ETC equipment at the Hasuda Smart IC on Out-bound lane.
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.
