What do city or state road maps primarily portray?

City or state road maps are designed primarily to provide a visual representation of roadways, paths, and thoroughfares, as well as landmarks and directions that assist travelers in navigating from one point to another. These maps include essential features such as highways, streets, bridges, and important locations like parks, hospitals, and government buildings, making them functional tools for navigation and orientation within urban and rural areas.

In contrast, historical significance pertains to events or landmarks of cultural importance that are not the primary focus of road maps. Demographic information relates to data about populations within certain areas, which does not appear in standard road maps. Natural resources, like minerals or water bodies, are also not depicted on these maps, as the primary purpose is to facilitate travel. Thus, the portrayal of roads, landmarks, and directional information solidifies why this choice is correct.
