Longest Highways in India 2025: Top 10 Longest National Highways List & Details

India is expanding quickly and constructing a strong infrastructure, including the longest roads in India, to link its many regions. New highways are being built quickly. These highways connect large cities. Since the longest national highways link India’s eastern, western, southern, and northern regions, they have evolved into the backbone of the country’s road system. 

These highways connect both small and large cities. In addition, they facilitate quick and simple travel. Hence, the National Highways Authority of India (NHAI), which oversees this road network from building to upkeep, deserves all the credit for this. 

When it comes to a nation’s infrastructure development, national highways are crucial. There are numerous national highways in India. India has approximately 599 national highways, which have a combined length of 1,46,145 km.
