Mount Kop Tunnel (Turkish: Kop Dağı Tüneli) is a road tunnel under construction located on the province border of Bayburt and Erzurum as part of the route between Maden, Bayburt in the northwest and Aşkale, Erzurum in the southeast in Eastern Anatolia Region, Turkey.
Situated on the Mount Kop of Pontic Mountains, it is a 6500m (21,300feet)-long twin-tube tunnel. The cost of the construction is estimated to be 319 million.
It was built to bypass the Kop Pass at 2409m (7,904feet) elevation with hairpin turns. The tunnel will also eliminate the four-month-long traffic inaccessibility during the winter months due to harsh climatic conditions by heavy snow fall, icing and fog. It will shorten the route about 6km (04miles) and reduce the travel time to one hour. The tunnel is situated at 2050m (6,730feet) elevation.
The groundbreaking ceremony was held in presence of Minister of Transport, Maritime and Communication Binali Yıldırım on 23 August 2012. Excavation works progress about 20m (70feet) daily in each tunnel tube. Opening of the tunnel is scheduled end of 2015.Currently, 150 personnel are at work.
