Mumbai, June 10: Shiv Sena (UBT) MP Sanjay Raut has demanded that the two portals of the Zojila Tunnel, linking the Kashmir Valley with Ladakh, be named after Brigadier Mohammed Usman, a 1947-48 Indo-Pak war hero, and Samrat Lalitaditya Muktapida, the 8th-century ruler of Kashmir. The Rs 6,800-crore Zojila tunnel, Asia's longest tunnel connecting the Kashmir Valley to Ladakh, on Tuesday achieved a significant breakthrough with a blast breaking through the last 2.5 metres of the 13-km high-altitude infrastructure project that cuts through the Himalayas. Union Minister for Road Transport and Highways Nitin Gadkari performed the breakthrough blasting of the main tunnel being constructed at an altitude of 11,578 feet above sea level, 24 km from Sonamarg and 103 km from Srinagar.
