Istanbul’s Eurasia Tunnel opens for test drive
Asphalt work for the tunnel was completed before the first passage. The construction of U-turns in the Kazlıçeşme area on the European side, as well as underground tunnels in the Samatya and Yenikapı areas, have also reached the final stage.
In addition, signboards displaying tunnel destinations have been placed on the roads between Sarayburnu and Kazlıçeşme and between Harem and Göztepe.
Drivers will be able to use the tunnel after paying tolls at automatic toll collection systems, in a similar method used on other cross-strait bridges in the city. Drilling works for a roadway tunnel were completed on August 24.
The 3.34-km-long tunnel under the sea, which is also dubbed the “Istanbul Straight Road Crossing Project” will connect the two continents for a second time.
The total distance of the tunnel will be 5.4 kilometers, 3.34 kilometers of which are under the sea. With the access roads, the Eurasia Tunnel Project’s total distance will be 14.6 kilometers.
At its deepest point, the tunnel will be 106.4 meters below the surface.
With the new tunnel, the travel time between Kazlıçeşme on the European side and Göztepe on the Asian side by car will decrease from around 100 minutes at present during rush hour to just 15.
This will make a positive contribution to the economy by decreasing fuel consumption amounts as well as carbon emission amounts, according to those leading the project.
The project is being constructed using a build-operate-transfer (BOT) model that will ultimately cost $1.2 billion. Some $960 million of the amount was provided through international loans, while the remaining amount was financed by the project holders, Yapı Merkezi and SK E&K. ■
