December 2006 landslide
On 16 December 2006, a massive landslide which occurred in the Siriucommune near kilometer 81 rendered DN10 unusable in that area, as some 5000 m³ of dirt flooded the road. The road was cleared and became available again by 22 December, a week after the landslide occurred.[1]
