General Information
Location
Istanbul, line running from Mecidiyeköy to Mahmutbey through six districts
Employer
İstanbul Büyükşehir Belediyesi
Project Scale
17.5 km main line
Infrastructure Components
15 stations32.9 km of tunnels (16 km of TBM excavation and 16.9 km of NATM excavation)A total of 929 m of viaducts in Kağıthane and Alibeyköy
Function
An integrated metro linking densely populated European Side districts
Linking Istanbul's busiest residential and business centers on the European Side, Mecidiyeköy Mahmutbey Metro is a major modern urban transport project.
Architectural and Engineering Details
The line includes 32.9 km of tunnels and viaducts totaling 929 m in Kağıthane and Alibeyköy. Modern station designs, accessible structures and passenger comfort solutions completed the project.
Technologies and Innovations Used
The line has fully automatic driverless technology, advanced signaling, ventilation and safety systems. Modern TBMs and high safety standards were used in tunneling.
Special Solutions
Designed for Istanbul's dense urban fabric, the line integrates with multimodal public transport, giving passengers easy access to Marmaray, Metrobus and other metro lines.
Project Stages and Solutions
Construction Stages
01
32.8 km of tunnel excavation
02
Construction of 15 stations
03
Construction of 929 m of viaducts in Kağıthane and Alibeyköy
04
Integration of electrification, signaling and driverless systems
Solutions
Day and night schedules advanced work in busy city areas. Tunnels and viaducts were completed to international standards despite difficult urban conditions.
Sustainability
Economic and Social Impact
Connecting business and residential centers significantly shortened daily journeys.
Greater public transport capacity reduced congestion and supported the city economy.
Shorter journeys reduced fuel consumption and individual costs.
Sustainability and Environmental Sensitivity
Construction Period
TBMs reduced dust, vibration and noise during tunneling, minimizing environmental impacts.
Excavation management plans classified excavated materials for filling and reuse.
Prefabricated viaduct elements reduced material waste and construction time.
Water recovery and energy efficiency measures were introduced on site.
Noise and vibration monitoring with regular reporting protected residents in dense urban areas.
Sourcing most materials and labor locally reduced carbon footprint and logistical emissions.
Operational Period
Electric, driverless, energy efficient systems significantly reduced carbon emissions.
Greater public transport use reduced private car traffic, associated emissions and noise.
Durable infrastructure solutions reduced maintenance and improved resource efficiency.
The 17.5 km main line runs from Mecidiyeköy to Mahmutbey through Şişli, Kağıthane, Eyüp, Gaziosmanpaşa, Esenler and Bağcılar.
