59°35′17.84″N 150°49′54.12″E﻿ / ﻿59.5882889°N 150.8317000°E﻿ / 59.5882889; 150.8317000
The R504 Kolyma Highway (Russian: 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 has been colloquially called the Road of Bones (Russian: Дорога Костей Doróga Kostéy). Locally, the road is known as the Kolyma Route (Russian: Колымская трасса Kolýmskaya trássa).

## History

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.
It has been widely claimed that an estimated 250,000–1,000,000 imprisoned labourers who died while constructing it were laid beneath or around the road, although documented sources have yet to confirm this with evidence of remains. 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.
Records indicate 10,251 people died in the Kolyma region prison system in 1938 from various official causes, mainly disease. The CIA's initial 1950's estimate of 3 million victims is stated to be flawed in Martin Bollinger's book on Kolyma prison labor. Norman Polmar's review of that book refers to 130,000 deaths.

## Present

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.

## Road to Chukotka

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 1,800 kilometres (1,100 mi) of road. The construction of the first 50 kilometers of the road started in 2012.
