Ordu Nefise Akçelik Tunnel (Turkish: Ordu Nefise Akçelik Tüneli), originally Hapan Tunnel, (Turkish: Hapan Tüneli) is a highway tunnel constructed in Ordu Province, northern Turkey. With its length of 3,825 m (12,549 ft), it is the country's longest tunnel.[1] The tunnel is named in honor of the Turkish female civil engineer and earth scientist Nefise Akçelik (1955-2003).
Construction
Ordu Nefise Akçelik Tunnel is part of the Samsun-Ordu Highway within the Black Sea Coastal Highway, of which construction was carried out by the Turkish Nurol-Tekfen-Yüksel joint venture.[1] The cost of the tunnel totalled to TL 361 million (approx. US$265 million as of 2007 exchange rate). The 3,805 and 3,825 m (12,484 and 12,549 ft)-long twin-tube tunnel carrying two lanes of traffic in each direction is flanked by 170–135 m (558–443 ft)-long Tekkebak Tunnel in the west and 310–314 m (1,017–1,030 ft)-long Asarkayası Tunnel in the east on the same highway. Traffic in the tunnel is controlled by 81 cameras at 16 different stations.[2]
The tunnel crosses mountainous area between the settlements Yarlı and Kırlı in Perşembe district of Ordu Province at 220 m (720 ft) elevation. It allows a short cut of 15 km (9.3 mi) between the town Fatsa and the city of Ordu saving one and half hours driving time.[3][2]
Naming and opening to traffic
Originally, the tunnel was named Hapan Tunnel. Its name was changed to Nefise Akçelik (1955-2003) in honor of the female civil engineer and earth scientist, who, working at the General Directorate of Highways, contributed much to the construction of tunnels in Turkey.[4]Finally, it was officially renamed Ordu Nefise Akçelik Tunnel in March 2007.[5]
The tunnel was opened to traffic on April 7, 2007 by Turkish Prime Minister Recep Tayyip Erdoğan.[2] Dangerous goods carriers are not permitted to use the tunnel.[6]
