Dr. Syama Prasad Mookerjee tunnel
Snowfall and avalanche in winter at Patnitop used to obstruct the Jammu-Srinagar National Highway a few times every winter and causes long queues of vehicles, sometimes for days. These problems were mitigated by the opening of the [[Chenani-Nashri Tunnel|Dr. Syama Prasad Mookerjee ]. At 9.2 km (6 mi), it is India's longest road tunnel. It starts from about 2 km (1 mi) from Chenani town south of Patnitop to Nashri village north of Patnitop, reducing the distance from Jammu to Srinagar by 31 km (19 mi) and bypassing Patnitop.
