By providing a direct, underground route under the Bosphorus, it would alleviate congestion on the bridges and offer a faster, more reliable way to cross between the continents. The tunnel was designed to reduce travel times significantly. What used to take an hour or more could now be done in just 15 minutes! This time savings is a huge benefit for commuters, businesses, and tourists alike. Imagine being able to get to that important meeting or catch that flight without having to worry about being stuck in traffic for hours. Moreover, the Eurasia Tunnel was part of a larger plan to improve Istanbul's overall transportation infrastructure. It complements other projects, such as the Marmaray rail line, which also runs under the Bosphorus, and the Yavuz Sultan Selim Bridge, the city's third bridge. These projects work together to create a more integrated and efficient transportation network. The construction of the Eurasia Tunnel also brought economic benefits to the region. The project created jobs during the construction phase and continues to support employment through its operation and maintenance. Furthermore, the improved transportation links have boosted trade and commerce between the European and Asian sides of Istanbul. In essence, the Eurasia Tunnel was built to address the challenges of a growing city, improve transportation efficiency, reduce congestion, and boost the economy.
