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.
