context_page_description: The Maryland highway system is a network of highways owned and maintained by the U.S. state of Maryland. In addition to the nationally numbered Interstate Highways and U.S. Highways, the highway system consists of a network of Maryland state-numbered highways. All three types of highways together provide access to all incorporated and unincorporated areas in all 23 counties of Maryland as well as the independent city of Baltimore.
context_section_description: There are other systems of highways in Maryland that are not marked but are numbered internally.
  County highways: All 23 counties have internal numerical designations for all highways under their jurisdiction.
  Municipal highways: Every city, town, and village maintains an internal system of numerically designated municipal streets.
  Federal government or agency highways: Highways maintained by the federal government or agencies such as the Maryland-National Capital Park and Planning Commission are designated inventory numbers.  Examples of highways within this category include parkways, such as the Clara Barton Parkway or Sligo Creek Parkway; streets on federal research campuses, such as those of the National Institutes of Health or Goddard Space Flight Center; roads on military bases, such as those on Fort Meade; and roads within reservations of the National Park Service, such as Bayberry Drive within Assateague Island National Seashore.
  State reservation highways: Highways maintained by non-highways agencies of the state of Maryland.  Examples of highways within this categories include streets on state university campuses, access roads to state parks and state forests, and highways within state-owned airports.
