Turkish President Recep Tayyip Erdoğan inaugurated a 69-kilometer metro line in Istanbul on Friday, marking the completion of one of the world’s longest metro systems. The newly opened Halkalı-Arnavutköy section significantly improves public transportation access across the city. Officials state the line will reduce travel time to the airport to just 30 minutes. This expansion is part of a larger infrastructure project aimed at easing congestion and improving connectivity within Istanbul. The project represents a substantial investment in the city’s transportation network. Further phases of the metro line are planned for future completion, continuing to expand Istanbul’s rail infrastructure. The completed line is expected to benefit millions of commuters daily.
