* R-504 Kolyma Highway (M56): Yakutsk to Never (Far East): Known as the "Road of Bones," large stretches are gravel or dirt, turning to mud during the spring/autumn thaws. Permafrost melt causes ruts in the highway and sinkholes, isolating mining communities. Winter freezes make the highway a treacherous ice track, with no cell service or fuel for hundreds of miles/kilometers.<ref>[https://grok.com/share/c2hhcmQtNA%3D%3D_74ca6f68-bae8-4965-af49-c2a379d4d702 Problems with the Russian federal highways]</ref>
