The D915 road begins in the Of district of Trabzon, crosses the Eastern Black Sea Mountains, and ends in the Aşkale district of Erzurum. Spanning approximately 180 kilometers, the Soğanlı Pass at Demirkapı location between Çaykara and Bayburt, at an elevation of 2330 meters, is regarded as one of the most dangerous roads in the world. Built during the Russian occupation of 1914 with forced labor from the local population, this route frequently experiences natural hazards such as avalanches and landslides, especially during winter months. The Derebaşı Curves along the road present drivers with extreme challenges, featuring dozens of sharp turns along steep cliffs that cannot be navigated in a single maneuver. One of the greatest difficulties on this road is its variable weather conditions. The humid climate of the Black Sea region causes fog, rain, and snowfall for much of the year. The absence of protective barriers adds an additional layer of danger for drivers and passengers.
