The section where this work will be carried out is a single lane, and since construction cannot be carried out under normal lane restrictions, it is necessary to work with the ramp closed.
Therefore, in order to minimize inconvenience to customers, the ramp will be closed at night when traffic is light, and construction will be carried out intensively and efficiently.
We ask for your understanding and cooperation as this work is necessary for safe and comfortable use of Expressway.
