Tekkebak Tunnel

Tekkebak Tunnel (Turkish: Tekkebak Tüneli), is a highway tunnel constructed in Ordu Province, northern Turkey.

Tekkebak 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. The 170 and 135 m (558 and 443 ft)-long twin-tube tunnel carrying two lanes of traffic in each direction is flanked by 261–257 m (856–843 ft)-long Kozbükü Tunnel in the west and 3,805–3,825 m (12,484–12,549 ft)-long Ordu Nefise Akçelik Tunnel in the east on the same highway.

The tunnel was opened to traffic on April 7, 2007 by Turkish Prime Minister Recep Tayyip Erdoğan. Dangerous goods carriers are not permitted to use the tunnel.
