Disclaimer: Lengths/Ranks may marginally differ due to new developments or renumbering by NHAI.

National highways are the arteries of the economy in India, and the most massive expansion and renumbering of the network has taken place in the last decade. And as of 2026, the list in terms of longest highways hasn’t changed much with the new National Highway Authority of India (NHAI) classification.

National Highway 44 (NH 44) is the longest highway in India, extending from the northern most tip to the southern end of the country.

Key Highlights of India’s Major Routes

AT A GLANCE:CAN MORE SECTIONS OF THESE MAJOR ROUTES IN INDIA BE TRAVERSED AS A NON-STOP DRIVE?

NH 44 (The North-South Corridor):- This is the mother of all indian-girls soload road trips. It was created by also combining seven previous ancient highways (one being the famous NH 7). From the snow-clad Himalayas of Srinagar, the journey ends at the tip of the Indian Ocean in Kanyakumari.

The East-West Corridor: NH 27 This highway is the primary lifeline between Western India (Gujarat) and the North-East (Assam). A significant passageway for both logistics and commerce

Golden Quadrilateral: Most of the highways mentioned above (eg. NH 48, NH 16, NH 19) comprise the “Golden Quadrilateral” linking the four major metros of India, namely Delhi, Mumbai, Chennai, and Kolkata.

Renumbering Note: You may be confused if you remember the old highway names! In India, a new system was adopted in 2010.

North-South are even numbers (like NH 44).

East-West roads are numbered with odd numbers (e.g. NH 27)

Modern “Shortest” Records

Talking of longest, India also has shortest strategic highway. NH 118 and NH 548 are some of the shortest in the country, both spanning merely about 5 km.

🛣️ India’s Highway Giants

Which is the Longest Highway NH 7 or NH 44?

NH 44 is the longest. NH 7 had been the longest at one point in time in Indian history but was again merged with some six other highways(which were corollary numbered to NH 1A, NH 2 etc.) to form the current NH 44. The highway now spans 4,112 km from Srinagar to Kanyakumari.

So, how does the updated numbering system work?

Now India is functioning on a system that carves the routing up in such a logical way that the drivers are able to find their way in no time:

East-West (even numbers; 2, 44, 48) As we go from east to west the numbers are increased (e.g. NH 2 is located in northeast while NH 68 is located in Rajasthan).

E-W Odd Numbers (9, 27, 33): These are the highways that go East-West. North has a structural number of 1; South, a 3; the numbers rise sequentially between the two.

THREE DIGIT NUMBERS (144, 244): These are secondary highways or branches. An example is NH 144 which is a branch of NH 44.

What is the most “safe” long highway in India?

According to many logistics experts one of the safest major highways is NH 30 (Sitarganj to Ibrahimpatnam). Being less busy as compared to high traffic corridors like NH 44 or NH 48, it has better planned interchanges and relatively lower accident rate too.

What is the “Golden Quadrilateral”?

It is a huge 5,846 km net connecting four “corners” of India i.e. Delhi, Mumbai, Chennai, and Kolkata. Although not one continuous highway, it utilises certain sections of the longest routes such as NH 48 and NH 19 to ensure connectivity among the key economic zones of the country.

🚦 Quick Facts & Milestones

🏔️ Records and Extremes

Which is now the highest motorable road in India?

The Border Roads Organisation (BRO) shattered its own record in late 2025. Located at a staggering height of 19,300 feet the world’s highest motorable road now lies at Mig La Pass in Ladakh. This made it higher than Umling La (19,024 ft) which previously held the record.

Which is the longest road tunnel in India?

The longest still is Dr. Syama Prasad Mookerjee Tunnel (or Chenani-Nashri Tunnel) on NH 44 with a length of 9.28 km long. Its keeps its significance when winter takes a toll on our plains, as it avoids the snow hit zones between Jammu and Srinagar.

Note: Zojila Tunnel(14.2 km) is being constructed and will replace this title once it gets fully commissioned.

Which is the longest bridge over water in India?

Built in 2021, the longest is the Atal Setu (Mumbai trans harbor link), which is 21.8 km long. Strictly for river bridges, the Dhola-Sadiya Bridge (part of NH 115) in Assam, currently holds the first position at 9.15 km.

🛰️ Contemporary Toll & Tech[ Updates 2026-2023]

What is “FASTag Annual Pass”?

Another feature introduced recently (August 2025) includes a one-time fee to entitlement private vehicle owners to ₹3,075 (rate from April 1, 2026). The pass costs $88, good for 200 toll crossings or one year, whichever comes first. It saves a lot of money relying on the highway often.

Is cash payment at tolls still acceptable?

Not really. As of April 2024, India has progressed towards 100% digital payments. You will be charged double the toll via UPI or other digital mediums if you enter a FASTag lane without a functional tag.

🛣️ The “Next Gen” Highways

Which is the most modern expressway in India?

Best in the country has to be the Delhi-Mumbai Expressway (where NH 48 is only a part, along with a number of new sections) It would cut the travel time between the two metros from 24 hours to 12 hours once fully functional. The highway [has also] includes animal overpasses (first in Asia).

Why do we have so many “A, B, or C” suffixes on highway numbers?

NH 44A means it is a secondary branch or called as “spur” of the main highway (NH 44) These typically link the primary highway to a significant adjacent city, harbor, or airport.
