NH-15 Four-Laning Cleared, Mangaldai Bypass Faces Delay
The government has approved a plan to make a big road called NH-15 into a four-lane highway in Assam, India.
This road goes from Baihata Chariali to Mission Chariali and will cost about Rs 470 crore.
A company called Vensar Constructions is building a bypass near Mangaldai, but they are behind schedule.
They were supposed to finish by April 2025, but got an extension to March 2026.
However, as of January 2026, they have only completed about 59% of the work, so it's unlikely they will finish on time.
The road is important for making travel easier in the area.
NH-15 upgrade to four-lane highway approved, costing Rs 470 crore.
Mangaldai bypass construction delayed, only 58.92% complete as of January 12, 2026.
Original deadline for bypass was April 27, 2025, extended to March 1, 2026.
Bypass construction started April 28, 2023, by Vensar Constructions Company Ltd.
Financial progress for bypass is 38.13%, with Rs 108.42 crore released so far.
