Turkey is taking steady steps towards achieving an ambitious vision of connecting the continents of Asia and Europe through the Grand Istanbul Tunnel, expected to open in 2028. This massive project serves as a new vital artery aimed at facilitating traffic flow and enhancing the transportation network in the city, which will have a positive impact on the Turkish economy.
A strategic location connecting two parts of Istanbul :
The Grand Istanbul Tunnel is located under the Bosphorus Strait, one of the most important waterways in the world, separating the European and Asian continents. Stretching over 14.6 kilometers, it will connect the European side of Istanbul with the Asian side, creating a new opportunity to facilitate traffic flow between these two sides.
Unique design meeting various transportation needs :
The Grand Tunnel of Istanbul includes three lanes on three levels, two dedicated to cars and one for trains. This unique design enables smooth traffic flow, allowing cars to cross the tunnel at speeds of up to 120 kilometers per hour, while trains transport passengers between city sections at 160 kilometers per hour.
Economic and Social Importance :
The Istanbul Grand Tunnel is a strategic project of significant economic and social importance. Economically, the tunnel is expected to enhance trade and tourism between Asia and Europe, create new job opportunities, and stimulate economic growth in Turkey. Socially, the tunnel will reduce traffic congestion in Istanbul, thus improving the quality of life for city residents and reducing environmental pollution.
The impact of Istanbul's giant tunnel on property prices.
The completion of the giant Istanbul tunnel project is expected to raise the price per square meter in the European areas of Istanbul, especially those directly connected to it. Constructing a tunnel under the sea will facilitate easy access to these areas from various parts of the city, attracting more residents and investors. Furthermore, the tunnel will create new opportunities for economic and touristic development in the region, leading to increased property values.
Other factors influencing real estate prices.
There are several other factors that will contribute to the increase in property values in European areas of Istanbul after the completion of the giant Istanbul tunnel project. For example, there will be an increase in the number of residents choosing to live in these areas due to the ease of access through the tunnel. Additionally, there will be an increase in the number of companies and establishments establishing themselves in these areas due to the new economic development opportunities the tunnel will provide.
