D.550 is a north-to-south state road in Turkey. It runs mostly along the west coast of Turkey. It starts at Edirne and ends in Muğla. The first of the road are in the European part of Turkey. Between Eceabat and Çanakkale, it passes over the Strait of Çanakkale (popularly known as Dardanelles) by ferryboat. The rest of the road is in the Asiatic (so called Anatolia) portion of Turkey. Being a north to east road it crosses the major west to east roads in Turkey like D.200 in Çanakkale and D.400 in İzmir. It shares the same itinerary with D.100 between Edirne and Havsa at the north and the same itinerary with D.400 between Yatağan and Muğla at the south.
