Crosses Bihar.
Through Gopalganj and Bettiah.
Why it matters
A short national highway across north-western Bihar between Gopalganj and Bettiah, through the Gandak plain. This is flood country — the Gandak and its tributaries cut the district roads most monsoons — so an all-weather highway between the two district towns matters more here than its length suggests.
Good to know
- Connects the district towns of Gopalganj and Bettiah in north-western Bihar.
- Crosses the Gandak plain, which floods most monsoons.
- Bettiah is the gateway town for the Valmiki Tiger Reserve on the Nepal border.
- The area is one of the most densely populated rural districts in India.
