Kırkgeçit Tunnels ( Turkish: Kırkgeçit Tünelleri, literally "Forty-Passes tunnels") are a series of seven motorway tunnels crossing the Taurus Mountains on the province border of Niğde and Adana, Turkey.
The tunnels are located on the
Ankara-
Tarsus motorway
O-21
E90 between
Kemerhisar and
Pozantı connecting the
Central Anatolia Region with the
Mediterranean Region. Five of the tunnels in the north are in
Niğde Province while the remaining two are situated in
Adana Province. All the seven tunnels are twin bores and carry three lanes of traffic in each direction. 16 viaducts named Kırkgeçit Viaducts connect the tunnels in series. Dangerous goods carriers are not permitted to use the tunnels.
[1] The
Çakıt Tunnel follows the Kırkgeçit-7 Tunnel in direction Pozantı.
The tunnels were constructed as part of the motorway O-21 and were opened to traffic on March 12, 2009. The tunnels allow the travel time of the passage through the mountainous terrain drop from one-and-half hours before to 20 minutes. A saving of ₺110 million annually is calculated for the national economy. The tunnels enable a through-traffic on motorways from the Bulgarian border Kapıkule to the border crossings to Syria and Iraq. [2]
