The Sarıyer-Kilyos Tunnel is a 6.875 km long, double-tube, four-lane highway tunnel connecting Çayırbaşı and Uskumruköy/Kilyos, aiming to alleviate traffic in northern Istanbul. The project, targeted to open at the end of 2026, will reduce travel time from 35 minutes to 5 minutes and is integrated with the Northern Marmara Highway.
This is the operational leadership of the YSS Bridge, one of the widest bridges in the world, which operates 24/7 and involves the maintenance of its drainage systems, liquid waste discharge, and solid waste management processes. During this process, environmental cleaning and infrastructure protection are ensured to high safety standards without disrupting bridge traffic.
