3. Construction overview

In order to keep the road structure in good condition at the Aqua Line, which has been open for 24 years, we will carry out tunnel fall prevention work and inspection of the road structure. Since it is not possible to carry out construction and inspection under normal lane regulations, it is necessary to close the road and carry out the work.
Therefore, in order to avoid inconvenience to customers as much as possible, we will close traffic on weekday nights when traffic is light and carry out construction intensively and efficiently. We ask for your understanding and cooperation as this work is necessary to use the Expressway safely and comfortably.
