Türkiye completed its longest and fastest metro line on Friday with the opening of the final section of the project that further expands Istanbul's rail transport network and strengthens links between the city center and its main airport.
President Recep Tayyip Erdoğan attended the inauguration of the 22-kilometer (13.7-mile) Halkalı-Arnavutköy section, the last phase of the project.
That brings the total length of the fully underground Gayrettepe-Istanbul Airport-Halkalı line to 69 km.
The metro line will operate at speeds of up to 120 km per hour, making it Türkiye's fastest metro route and one of the longest underground airport metro connections in the world.
The newly opened section includes five stations: Ibn Haldun University, Kayaşehir, Olimpiyatköy, Halkalı Stadium and Halkalı.
