According to the department, the newly opened highway is a vital component of the region's transportation network, featuring a high-speed highway with two lanes in each direction and a design speed of 100 kilometers per hour.

The highway project started construction in March 2019, with the line crossing the Yarlung Tsangpo River, running parallel to the Lhasa-Nyingchi Railway and National Highway G318. Currently, high-grade highways connect the regional capital Lhasa with the region's cities of Nyingchi, Lhokha, Nagchu and Shigatse.
