Turkish Transport Minister Abdulkadir Uraloglu announced the Istanbul Northern Railway Crossing Project, with a tender set for October 14. The 122.3 km line will connect Sabiha Gokcen and Istanbul airports via the Yavuz Sultan Selim Bridge, backed by $6.75 billion in international financing.
Project Scope
The 122.3 km double-track main line will include 36.2 km of twin-tube TBM tunnels, 23.3 km of twin-track NATM tunnels, 3.7 km of cut-and-cover tunnels, 22.1 km of viaducts, and 40 bridges. The route starts at the Marmaray line in Cayirova, passes through Sabiha Gokcen Airport, Yavuz Sultan Selim Bridge, and Istanbul Airport, ending in Catalca. It will integrate with the Halkali-Cerkezkoy high-speed line under construction.
Financing Details
Uraloglu said preliminary agreements with six international financial institutions will provide $6.75 billion, making it Turkey's largest externally financed railway project. The line is expected to carry 33 million passengers and 30 million tons of freight annually, easing Marmaray congestion and boosting capacity on the Middle Corridor.
