M20 (Istanbul Metro)

The M20, officially referred to as the M20 Sefaköy–TÜYAP Metro Line is a planned rapid transit line in Istanbul.

The line was originally conceived as an extension to the M2 line but was later made into its own lines due to conflict and lack of communication between the opposition-controlled Istanbul Metropolitan Municipality and the government-controlled Ministry of Transport and Infrastructure and was later given the line code M20 on the vision map.

History
The line will be crucial for the districts it passes through with a total population of 3.5 million people, who currently have no alternative other than the Metrobus. Works on the line has not started yet, the plans and projects prepared by Istanbul Metropolitan Municipality (IMM) were not approved by General Directorate of the Infrastructural Investment (AYGM) for a period spanning more than a year. As a result of long discussions, the environmental impact assessment report process started on August 5, 2022. In the statement made by the Mayor of Istanbul, Ekrem İmamoğlu, he announced that the AYGM approval was received and that they are currently working on approval from the treasury.
