M4 Kadıköy-Kartal
With its construction starting in 2008, the Kadikoy-Kartal Metro Line has an approximate length of 22.7 km and a total of 16 stations. The line’s Depot Site and Maintenance Workshop are located between Maltepe and Huzurevi Stations and on the coastal side of the main line. The line is entirely underground including the Maltepe Depot Site and Maintenance Workshop.
As a result of estimated cost increase, tunnels up to the Kaynarca district have been bored using the TBMs. With the separate Kartal-Kaynarca tender for civil and electromechanical works, the length of the line will ultimately reach to 26.5 km and the total number of stations to 19.
