Kullu: The 13,050 feet high Rohtang Pass was today thrown open for all types of vehicles. SK Doon, Commandant, Border Roads Organisation (BRO), said that the road was fit for vehicles but the organization would restrict traffic until next week so that the men and machinery belonging to BRO was withdrawn from the road. It may be recalled that the Rohtang pass remains closed due to heavy snowfall every winter for about six months. This year the Pass has been opened within five months. HRTC authorities here said that they did not have official information about the opening of Rohtang Pass and would start its bus operations only after official clearance was given.
