The upgrade comprised civil as well as electro-mechanical work. It also includes 76 high-definition CCTV cameras, smoke and fire sensors, SCADA systems and a centralised monitoring room for real-time supervision, a senior official said.

It acts as an alternate route to National Highway 44. Vehicles that are not allowed to cross the newly constructed Quazikund-Banihal tunnel such as oil tankers, explosive-laden and gasoline vehicles, will use this tunnel, the ministry said.
