The Anadyr Highway is a highway on the territory of Magadan Oblast and the Chukotka Autonomous Okrug from the R504 Kolyma Highway to the city of Anadyr with branches to Bilibino, Komsomolsky and Egvekinot. In the Magadan Region it is numbered 44H-3; in Chukotka the existing segments have the number 77K-022. The new highway will ensure the year-round connection of the Chukotka Autonomous District with the rest of Russia. Construction of the road in the Chukotka Autonomous District began in 2012. Construction in the Magadan Region began in 2015. Route The route starts from the R504 Kolyma Highway, revitalizing the old road to Omsukchan, then passes through Omolon, Ilirney, Palyavaam, then along the existing extended winter road to Valunistoye mine, where it turns south towards Anadyr. The total length is about , of which pass through the Magadan Region, and about through Chukotka. Features The road has the lowest technical category, without asphalt. The roadway will be treated with binder additives, which increase the resistance of the upper layer. The width of the single-lane roadway is , with passing areas. The roadsides are equipped with snow protection fences, signal posts and road signs. The maximum speed is limited to . Construction The whole route passes through a territory bounded by permafrost, therefore, the laying of the roadbed is done without disrupting the integrity of the moss-vegetation layer of the tundra, which is a good heat insulator that does not allow defrosting of the upper layer of permafrost, which can lead to the destruction of the road. In the marshy areas, geotextiles and geogrids are also used; the slopes of the embankment and the culverts are strengthened by multicellular mattresses. Aggregate for the roadbed is mined in roadside quarries, while in some places drilling and blasting are necessary. Engineering materials are imported during the period of summer navigation from the central regions of the country. Due to extreme climatic conditions, construction is suspended in summer during heavy rains, in winter in cases of particularly low air temperature and severe snowstorms. Current state A bridge across the Palyavaam River was built in 2003, by the Artel of Miners of Chukotka LLC. A contract was signed with Stroydor company about building the Omsukchan–Omolon road and fixing the older Gerba–Omsukchan road, for RUB 1.53 bn. Works have been started at Omsukchan. By 2018, the total length of the constructed sections of the route should
