Eurasia Tunnel Istanbul: Visiting Hours, Tickets, and Comprehensive Travel Guide
Date: 14/06/2025
Introduction
The Eurasia Tunnel in Istanbul, Turkey, is a landmark of modern engineering that physically and symbolically connects Europe and Asia beneath the Bosphorus Strait. Opened in 2016, this twin-deck, undersea road tunnel stretches 5.4 kilometers underwater, forming part of a 14.6-kilometer corridor between Kazlıçeşme (European side) and Göztepe (Asian side). Its construction has not only alleviated chronic congestion in one of the world’s most vibrant cities but also stands as a testament to Istanbul’s dynamic blend of history and modernity. This detailed guide explores visiting hours, ticketing, travel tips, engineering features, and more to help you make the most of your visit to the Eurasia Tunnel (Wikipedia; Arup; New Civil Engineer).

Historical Background and Development
Vision and Early Plans
The idea of connecting the two sides of Istanbul under the Bosphorus dates back to the late 19th century, when French engineer Simon Préault proposed an underwater tubular bridge for steam trains, patented by the Ottoman government. However, technological and financial limitations postponed realization for more than a century (Wikipedia).
Modern Conceptualization
The Eurasia Tunnel’s modern vision emerged from Istanbul’s 1997 Transportation Master Plan, which highlighted the necessity of a new Bosphorus crossing to manage escalating traffic. Following a 2003 pre-feasibility study and a comprehensive 2005 analysis, the project was officially launched in 2006 with a focus on connecting Kazlıçeşme and Göztepe (Network Industries Quarterly).
Design, Engineering, and Construction
Key features include:
- Double-deck tunnel: Two levels for eastbound and westbound traffic.
- Depth: Up to 106 meters below sea level, one of the world’s deepest road tunnels.
- Advanced seismic resilience: Designed to withstand Istanbul’s earthquake risks (Arup; GZ Consultants).
Construction began in 2011 via a public-private partnership at a cost of approximately $1.25 billion USD. The tunnel was completed and opened in December 2016 (Avrasya Tüneli).
