O-1 – O-9
- O-1 (İstanbul 1. Çevre yolu) Inner beltway of İstanbul
- O-2 (İstanbul 2. Çevre yolu) Outer beltway of İstanbul
- O-3 (Avrupa Otoyolu) Edirne - İstanbul
- O-4 (Anadolu Otoyolu) İstanbul - Ankara
O-20 – O-29
- O-20: (Ankara Çevre yolu) Beltway of Ankara
- O-21: (Tarsus-Ankara Otoyolu) Under construction, Tarsus - Bor, Niğde Motorway in use.
O-30 – O-39
