Answer:
building roads
Step-by-step explanation:
One of the main duty of the state employees is to oversee the building and maintenance of public infrastructures (such as public schools, roads, public parks, public bathrooms, etc).
Not all state employees have the power to determine which infrastructure should be build, most of them only hired as normal labors. If the citizens wanted to make a request regarding infrastructures, the best course of actions would be making petitions and give it to the nearest local government.
