What unit does the maintenance department belong to?

Sometimes when people pass a certain section of road, they will find a slogan about the maintenance unit of this section of road. Many people don't know what unit the locomotive depot is. Let me tell you in detail. The maintenance section is a public institution and is managed by the Highway Bureau. Highway maintenance is the unit entity of highway maintenance and management. Generally speaking, most highway systems are public institutions, which are subordinate to the Provincial Communications Department and managed by the Highway Bureau. The management order is Provincial Communications Department-Provincial Highway Bureau-Ordinary Highway Section-County Road Section-Maintenance Road Administration. The institutions of Yang Lu Road are facing reform, and the direction of reform is to divest public service and management functions, integrate with other institutions such as the Highway Bureau under the Transportation Bureau, and set up a comprehensive service center to manage urban and rural roads in a unified way. Peel off the maintenance service function that can be replaced by market and social services, change it to government purchase services, and implement the separation of enterprise management and protection. Institutions no longer undertake the functions of production, operation and social service. The maintenance section is a public institution, which is managed by the Highway Bureau and carries out the maintenance and management of roads.
