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 (referring to Autobahn) 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 (Devlet Yolları) are historical and free road network that are completely under the responsibility of the General Directorate of Highways except for urban sections (like the sections falling within the inner part of ring roads of Ankara, Istanbul or İzmir). Even if they mostly possess dual carriageways and interchanges, they also have some traffic lights and intersections.
Provincial roads (Il Yolları) 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.
Motorways: Motorway 3.796 km (January 2025) Dual carriageways: 29.673 km (January 2025) State Highways 30.832 km (January 2025) Provincial Roads 33.922 km (January 2025) Motorway Projects‐Vision 8.325 km (in 2053)
As of 2023, there are 471 tunnels (total length 665 km) and 9.660 bridges (total length 739 km) on the network.
Motorways
Turkey has national network of controlled-access highways; these motorways are called , singular , in Turkish. Most sections have three lanes in each direction and most are tolled. Older routes were built solely with state funds, while newer routes and routes under construction were developed through the build–operate–transfer (BOT; ) model, where private companies build and operate the highway for a specified period before transferring ownership to the state. This allows for private investment in highway infrastructure to support expansion and maintenance without immediate public expenditure.
