M14 (Istanbul Metro)

The M14, officially referred to as the M14 Altunizade - Küçüksu metro line is a 7.3 km long rapid transit line project on the Anatolian side of Istanbul, with Altunizade as the first station and Küçüksu as the last station.

When the project first came out, it was stated that the metro line would be built as a mini metro line between Kısıklı and Çamlıca Mosque, just like the M6 Levent - Boğaziçi University - Hisarüstü metro line. Though later on it was announced that the project got cancelled. After the Istanbul Metropolitan Municipality announced that this project was canceled, the Ministry of Transport and Infrastructure revised the project to be a standard metro line and undertook the construction of the project.

The line was previously planned to interchange with Line M12 at Kâzım Karabekir station. On 8 December 2023, Kâzım Karabekir station was canceled, 5 stations were added to the line and it was extended to Küçüksu.

On 28 December 2023, Minister of Transport and Infrastructure Abdulkadir Uraloğlu announced that the first phase of the project between Altunizade and Bosna Bulvarı would be completed by the end of 2025.
