3. Construction overview

In order to keep the road structures in good condition on the Aqualine, which has been open for 25 years, we will carry out construction work to prevent tunnels from falling off and inspections of the road structures. Since it is not possible to carry out construction work and inspections under normal lane restrictions, it is necessary to carry out the work while the roads are closed.
Therefore, in order to minimize inconvenience to customers, we will close the road at night on weekdays when there is little traffic, and carry out construction work intensively and efficiently. We ask for your understanding and cooperation as this work is necessary for safe and comfortable use of the Expressway.
