List of United States federally maintained roads

The Baltimore–Washington Parkway is maintained by the National Park Service.

The vast majority of roads in the United States are maintained by the state or lower-level agencies. However, some roads are maintained by the federal government. Most of these are minor roads in national parks and national forests, which are not listed here. However, a few roads have been developed to connect sites in the national park system or to protect routes of scenic or historic significance, and some roads in national parks are major enough to list.

National parkways:

• Baltimore–Washington Parkway south of Maryland Route 175
• Blue Ridge Parkway
• George Washington Memorial Parkway
• John D. Rockefeller, Jr. Memorial Parkway
• Natchez Trace Parkway
• Foothills Parkway
