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.

Possible extensions

There is a significant public interest in extending the East West Corridor from Silchar to Moreh through Jiribam and Imphal, and from Nagaon to Stilwell Road via Jorhat, Dibrugarh, Tinsukia, and Ledo. Implementing these two extensions could potentially enhance cross-border trade with South East Asia.
