Expressways & Major Streets In India

Expressways are the highest class of roads in the Indian road network. They are six- or eight-lane controlled-access highways (motorways or freeways), where entrance and exit is controlled by the use of slip roads (ramps) that are incorporated into the design of the highway.

Expressways are a more efficient way to move heavy amounts of traffic.

They have multiple lanes of traffic traveling in the same direction.

Interchanges (on/off ramps) take place of intersections

Expressways have controlled access for entering and exiting

Directions of travel are divided by a barrier of some type. (guardrails, cement barriers, grassy medians)

Driving on Expressways are safer than highways, However accidents occurred on expressways are usually more severe

Basic Characteristics

India has approximately 1,324 km of expressways. In addition to the initiatives taken up under NHDP-

Phase-VI to develop about 1,000 km length of Expressways, a target of developing about 500 km length of Expressways may be fixed for the 12th Plan (2017-2022).

The MORT&H has prepared a Master Plan for the National Expressways Network for a total length of about 18,637 km.

The Ministry of Road Transport and Highways is in the process of preparing a draft for creation of a National Expressways Authority of India (NEAI) on the lines of the National Highways Authority of India (NHAI)

Durgapur Expressway in the state of West Bengal, part of NH 2

Delhi-Gurgaon stretch of National Highway – 8 (NH-8). The 8-lane expressway connects Delhi to Gurgaon and IGIA

On 28 April 2010, the Ministry of Road Transport and Highways officially notified the rationalized number system of the national highway network in the Gazette of the Government of India. It is a systematic numbering scheme based on the orientation and the geographic location of the highway.

All East-West highways now have odd numbers, starting in the North and increasing in number towards the South. In other words, the greater the latitude the smaller the N-H number and vice-versa ie NH-1 in J&K and NH-87 in Tamil Nadu.

Re-numbering of NHs

Similarly, all North-South highways now have even numbers, starting in the East and increasing in number towards the West. In other words, the greater the longitude the smaller the NH number and vice-versa i.e NH-2 in the North-East States of India and NH-68 in Rajasthan & Gujarat.

Major highways have single- or double-digit numbers. Offshoots of these highways have triple digits (either with or without a suffix alphabet). For example, offshoots of NH 2 are numbered 102, 202, 302 and 502. Please note that the last two digits indicate the Major Highway

Re-numbering cont…

THREE digit numbered highways are secondary routes or branches of a main highway. For example, 144, 244, 344 etc will be the branches of the main National highway 44. Please note that since NH44 (NS Corridor) runs the length of the country from North to South a side shoot say 144 may be up north while something like 944 may be down south.

Suffixes A, B, C, D etc are added to the three digit sub highways to indicate very small spin-offs or stretches of sub-highways. For example, 966A, 527B etc
