○When rain continues for a long period of time (cumulative rainfall)
○ The combination of continuous rainfall and hourly rainfall exceeds a certain level (combined rainfall).
○ If strong winds that would hinder driving are observed.
○ If the effects of high waves are confirmed

*If a road closure is initiated, customers using service areas (SAs) and parking areas (PAs) within the closed section may be unable to move until the closure is lifted.
*The amount of rainfall so far has loosened the ground, increasing the risk of landslides.
Therefore, the road closure will only be lifted after a period of rain-free weather has passed, followed by inspections, work, and confirmation of safety.

Route and time selection for a comfortable drive

To make using Expressway as comfortable as possible while construction is underway, why not start selecting your route (detour) and time of use?
Each construction project has its own dedicated website, which provides information to help you travel comfortably, such as detours and congestion times, and this page explains how to make the most of the construction project website.

Expressway Renewal Project

The Expressway Renewal Project aims to maintain the expressway network's functions safely over the long term. This will be achieved by taking essential and effective measures from the perspective of minimizing the life cycle costs of main body structures (all costs required until a structure's purpose is completed), preventive maintenance (maintenance conducted before damage and malfunctions occur), and performance improvement.

NEXCO CENTRAL is working to fully implement a two-day weekend system at its construction sites.
