The section where this work is to be carried out is one lane, and it is not possible to carry out the work under normal lane regulations, so it is necessary to close the lamp and carry out the work.
Therefore, in order not to cause any inconvenience to customers, we will close the lamps on weekday nights when there is little traffic, and carry out the construction intensively and efficiently. This work is necessary to use Expressway safely and comfortably, so we ask for your understanding and cooperation.
