Ramban, May 26: The Srinagar–Jammu National Highway remained open for two-way movement of Light Motor Vehicles (LMVs) on Tuesday although traffic movement continued to remain slow at several stretches due to congestion, vehicle breakdowns, and the movement of nomadic herds between Ramban and Banihal. Traffic authorities said that, subject to fair weather and favourable road conditions, the highway would remain open for two-way movement of LMVs and heavy vehicles on Tuesday as well. Officials said heavy congestion was witnessed between Marog and Kishtwari Pather where single-lane road conditions created bottlenecks and hampered smooth vehicular movement.
