Kozbükü Tunnel (Turkish: Kozbükü Tüneli), is a highway tunnel constructed in Ordu Province, northern Turkey.[1]
Kozbükü Tunnel is part of the Samsun-Ordu Highway D.010 E70 within the Black Sea Coastal Highway, of which construction was carried out by the Turkish Nurol-Tekfen-Yüksel joint venture.[1] The 261 and 257 m (856 and 843 ft)-long twin-tube tunnel carrying two lanes of traffic in each direction is flanked by 116–150 m (381–492 ft)-long Kadıoğlu Tunnel in the west and 170–135 m (558–443 ft)-long Tekkebak Tunnel in the east on the same highway.[2]
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.[3]
