List of highways in Turkey


The highways in Turkey are divided into three types: motorways, state roads and provincial roads.

Types of roads

There are three types of intercity roads in Turkey:
Motorways are controlled-access highways that are officially named Otoyol. But it is not uncommon for people in Turkey to call them Otoban as this types of roads entered popular culture by the means of Turks in Germany. These roads depend on the General Directorate of Highways except those that are financed with a BOT model.
State roads are historical and free road network that are completely under the responsibility of the General Directorate of Highways except for urban sections. Even if they mostly possess dual carriageways and interchanges, they also have some traffic lights and intersections.
Provincial roads '' are highways of secondary importance linking districts within a province to each other, the provincial center, the districts in the neighboring provinces, the state roads, railway stations, seaports, and airports.
As of 2023, there are 471 tunnels and 9.660 bridges on the network.

Motorways

This map highlights different types of highways across Turkey as of October 1, 2024, classified by their funding and operational model:
Red: Highways that are open to service and funded by public resources.
Blue: Highways currently under construction, developed through the Build-Operate-Transfer model, where private companies build and operate the highway for a specified period before transferring ownership to the government.
Green: Highways that are already open to service and were developed using the BOT model, now operational and managed under this system.
The Build-Operate-Transfer model, known as "Yap-İşlet-Devret" in Turkish, allows for private investment in highway infrastructure to support expansion and maintenance without immediate public expenditure.

Provincial roads

Provincial roads are under the responsibility of KGM. These are the roads that connect the central district and counties within the borders of a province to each other and to the nearby district centers of neighboring provinces, state roads, train stations, ports and airports.
These are roads other than those under the responsibility of municipalities or other institutions and bear the license plate number of that province in the road identification number's first half.
