Every road and pipeline on Arctic permafrost, colored by how fast the ground underneath is actually warming — sampled live from a real 1km climate raster, not looked up.
Yakutsk's margin is not a random default. A peer-reviewed cost model (Streletskiy et al., Environmental Research Letters 2023) names it — alongside Vorkuta and Norilsk — as one of the Russian Arctic cities with the most infrastructure exposed to permafrost degradation. National estimates put roughly 40,000 km of roads and 9,500 km of pipelines on ground the Russian Academy of Sciences rates as at risk, with damage projections spanning $80–250 billion depending on the study and the year horizon (Arctic Portal; Eos, on pipeline repair costs alone).
Every one of those studies stops at a national or regional total — a single number for a landmass the size of Australia. None of them tells a pipeline operator or an insurer which specific kilometer is the one sitting on ground that is actively warming. This page answers that question live: pan to Yakutsk's own margin (61.5–62.5°N) and the same 5,990 km of real OSM road network splits into 4,177.8 km of stable class 12 bedrock, 1,785.4 km of class 22 — cool ground with a measured 25-year warming trend — and 26.8 km of class 21. That 1,785 km is not in the national total as a line item anywhere; it is the fraction of Yakutsk's own road network the aggregate $80–250bn figure is actually describing.
Who pays for this number. The buyers of a national aggregate are policy reports; the buyers of a per-corridor number are the parties who hold the asset: pipeline operators (Transneft, Gazprom's Arctic gas trunklines) who already budget geotechnical monitoring per kilometer of pipe, and the (re)insurers who underwrite that infrastructure and price risk per asset, not per country. Both groups pay engineering consultancies today for exactly this cross-reference, done by hand, asset by asset, from static geotechnical surveys that go stale between site visits. This page recomputes it live, for any corridor, from a public raster that updates with the underlying climate data — the gap it fills is refresh rate and coverage, not the existence of the question.
This is not a Russia-only question. Canada's Northwest Territories already reports $51 million a year in permafrost damage to public infrastructure, with 17% of Canadian roads on permafrost (≈7,200 km) rated at risk of significant thaw subsidence (CBC/NWT study; The Arctic Institute). The Inuvik–Tuktoyaktuk Highway — Canada's only public road reaching the Arctic Ocean, built in 2017 on continuous permafrost — is the same kind of asset as Yakutsk's network, for a Canadian territorial government and its engineering contractors instead of a Russian pipeline operator.
