The Great Istanbul Tunnel Project

The Great Istanbul Tunnel Project

The three-level subsea tunnel under Istanbul’s Bosphorus Strait will connect the city’s two sides (European and Anatolian) with one railway and two highways. Trains will pass through a tube in the middle, while tubes below and above will be for vehicular transit. The tunnel will be integrated into nine subway lines, the TEM Motorway, the E-5 Motorway and the Northern Marmara Motorway. Around 6.5 million passengers are expected to use the tunnel on a daily basis once it is completed in the next five years.
