TURKEY: An extension of Istanbul metro Line M3 running 6·2 km from Başakşehir Metrokent to Kayaşehir Merkez with three intermediate stations was opened by President Recep Tayyip Erdoğan on April 8.


The initial 11·6 km of Line M3 from Kirazlı to Başakşehir Metrokent opened in September 2013. Work on the extension was initially begun by the municipality, but the project was taken over by the Ministry of Transportation & Infrastructure in 2021 as part of a political tug-of-war between the national and city authorities.
