Road in eastern Russia

The R504 Kolyma Highway (Федеральная автомобильная дорога «Колыма», Federal'naya Avtomobil'naya Doroga «Kolyma», "Federal Automobile Highway 'Kolyma'"), part of the M56 route, is a road through the Russian Far East. It connects Magadan with the town of Nizhny Bestyakh, located on the eastern bank of the Lena River, opposite of Yakutsk. At Nizhny Bestyakh the Kolyma Highway connects to the Lena Highway. The Kolyma Highway is colloquially known as the Road of Bones (Russian: Дорога Костей Doróga Kostéy). Locally, the road is known as the Kolyma Route (Russian: Колымская трасса Kolýmskaya trássa).

The Dalstroy construction directorate built the Kolyma Highway during the Soviet Union's Stalinist era. Inmates of the Sevvostlag labour camp started the first stretch in 1932, and construction continued with the use of gulag labour until 1953. The road is treated as a memorial by some, as the bones of the estimated 250,0001,000,000 imprisoned labourers who died while constructing it were allegedly laid beneath or around the road, although documented sources have yet to confirm this through further evidence. As the road is built on permafrost, the popular rumor spread through western and dissident accounts is that interment into the fabric of the road was deemed more practical than digging new holes to bury the bodies of the dead.

In 2008, the road was granted Federal Road status and is now a frequently maintained all weather gravel road. When the road was upgraded, the route was changed to bypass the section from Kyubeme to Kadykchan via Tomtor, and instead pass from Kyubeme to Kadykchan via a more northern route through the town of Ust Nera. The old 420 km section via Tomtor was largely unmaintained; the 200 km section between Tomtor and Kadykchan was completely abandoned. This section is known as the Old Summer Road, and has fallen into disrepair, with washed out bridges and sections of road reclaimed by streams in summer. During winter, frozen rivers may assist river crossings. Old Summer Road remains one of the great challenges for adventuring motorcyclists and 4WDers. The area is extremely cold during the winter. The town of Oymyakon, approximately 100 km from the highway, is believed to be the coldest inhabited place on earth. The average low temperature in Oymyakon in January is −50°C. In 2020, a teenage motorist froze to death by following Google Maps directions to use the shorter but abandoned section of the road via Tomtor, on which his car broke down, and his surviving travel mate lost most of his limbs due to frostbite.

The Anadyr Highway project from the Kolyma Highway to Anadyr in Chukotka passes Omsukchan, Omolon, and Ilirney with branch roads to Bilibino and Egvekinot, involving construction of of road. The construction of the first 50 kilometers of the road started in 2012.
