This road connects the Northeastern Anatolia region of Turkey to the Black Sea. The D915 mountain road has many dangerous bends and descents.

According to legend, the D915 road was built by the Russian army using only hand tools. Although some parts at each end have been paved with asphalt, the majority of it is still made up of loose gravel. Initially, D915 doesn't appear too extreme, but as you travel from both ends, asphalt is replaced by gravel and the road becomes increasingly narrow and steep.
