Rothang La opened for traffic on the 15th .. only to close again today in heavy snowfall. Before the weather gods smote the road again the BRO guesstimate for clearing the road up to Sarchu was the April 20th. Video interview with SK Doon here on March 8th here , showing up close how media works :
SPEAKER VOICE : “BRO is hopeful to open the road by April 15th”
SK DOON ” …everything depends on weather conditions. Still , we should be able to clear the Rohtang and Baralacha La by April fifteenth – if everything agrees with the weather. If there is further snowfalls and problems with the weather , then the dates will be revised further…”
Note the heavy emphasis on how the weather rules , and no date is mentioned for the whole Manali-Leh highway – then compare with how this is interpreted in media & blogs.
