The project involves the balance work of four-laning the Kiratpur to Nerchowk section of NH-21, covering the stretch from Ch. 165+092 to Ch. 171+855 (North Bound), and from Km 0+000 to Km 12+750, as well as from Km 158+500 to Km 182+215, excluding the Sunder Nagar Bypass (Pkg-1). This critical infrastructure initiative spans across Punjab and Himachal Pradesh under EPC mode.

The successful completion of three major bridges, incorporating steel truss girders and RCC deck slabs, marks a significant achievement.
