The Salmankaş Tunnel (Turkish: Salmankaş Tüneli) is a road tunnel located on the province border of Gümüşhane and Bayburt connecting the provincial roads P.29-26 and P.69-75 on the route from Araklı, Trabzon via Dağbaşı, Trabzon to Uğrak, Bayburt in northeastern Turkey.

[1][2][3] Situated on the Mount Salmankaş of Pontic Mountains, it is a 4,150 m (13,620 ft)-long twin-tube tunnel.

[2][3][6] It was built to bypass the Salmankaş Pass at 2,280 m (7,480 ft) elevation, which is on the ancient Silk Road,[5] with extremely steep incline and to alleviate Black Sea Region's access to Eastern Anatolia Region.

The tunnel will also eliminate the six-month-long traffic inaccessibility during the winter months due to harsh climatic conditions by heavy snow fall, icing and fog.

[2][3][6] The groundbreaking ceremony was held in presence of Minister of Transport, Maritime and Communication Binali Yıldırım on 23 August 2012.
