Due to road widening works from Manali to Rohtang, Rohtang Pass will not be accessible for tourists on Tuesdays. Tourist traffic bound for the pass will be stopped at Kothi, 30km from Manali. The closure will be between 9am and 6pm, and will be in place till the road widening work is completed.

Since the road remains open till 9am, those travelling to Lahaul region and further to Ladakh, who normally leave early in the day may not be affected. Emergency vehicles and public transport buses from HRTC will be allowed to use the road even during the hours of closure.
If you are planning to visit Rohtang in near future, ensure that you the road to pass is open. Some early snow falls last week had temporarily shut down access to the pass.
