North–South and East–West Corridor. The North–South–East–West Corridor (NS-EW) is the largest ongoing highway project in India. It is the second phase of the National Highways Development Project (NHDP), and consists of building 7300 kilometers of four/six lane highways associating Srinagar, Kanyakumari, Kochi, Porbandar and Silchar, at a cost of US$12.317 billion ₹10,00,00,00,00,000(INR One lakh Crore). , 6875 of the 7142 kilometers project has been finished. 

In combination with the Golden Quadrilateral network, and port connectivity highways, the NS-EW Corridor forms a key part of the Indian highway network, connecting many of its important manufacturing, commerce and cultural centers. As of May 2012, India has completed and placed in use some 15,800 kilometers of such 4-lane highways.

The NS–EW project is managed by the National Highways Authority of India under the Ministry of Road Transport and Highways.

Major cities

Possible extensions
There is popular demand for the extension of the East West Corridor from Silchar to Moreh via Jiribam and Imphal, and from Nagaon to Stilwell Road via Jorhat, Dibrugarh, Tinsukia and Ledo. These two extensions may increase the cross border trade with South East Asia.
