Major Highways are express roads that are not freeways. In Turkey, most state roads are major highway; they always starts with D-xxx. Similar to freeways, there might be an E-x number assigned as well. Use the same naming convention as described for freeways in rural areas. In urban areas, a city name may be added. The latest directory of motorways is from 2014.
Minor Highways are mostly maintained by local authorities. There is no standard for road naming. We use this road type for through-going traffic or for longer distances connecting cities or towns.
Ramps are entrance and exit roads to highways and have special functions for routing instructions. See the explanation on Interchanges and other connecting segments for detailed information.
