French landslide closes key Andorra road for months
A major landslide near Ax‑les‑Thermes has blocked a key French road used by Andorra, prompting months‑long closure and environmental and economic concerns in the region.
In January 2026 a sizeable landslide on the RN‑20 road near Ax‑les‑Thermes in France released about 200 m³ of material and threatens a further 500 m³ fall, cutting off a vital route to Andorra. The closure has severely reduced traffic to Pas de la Casa and Grandvalira, with local businesses reporting up to 80% sales drops and significant losses in ski‑tourist days. Both Andorran and French authorities are conducting bi‑weekly inspections and assessing stabilization measures, while Andorra has introduced emergency aid measures. The event highlights growing environmental risks in the mountain region, driven by extreme weather and slope instability, and raises long‑term concerns about infrastructure resilience and cross‑border cooperation.
