[1] The project also includes the development of tunnels, bridges, elevated corridors, flyovers, overpasses, interchanges, bypasses, ring roads, etc.

to provide the shortest, jam-free & optimized connectivity to multiple places, it is a centrally-sponsored and funded Road and Highways project of the Government of India.

The total investment for 83,677 km (51,994 mi)[3] committed new highways is estimated at ₹10.63 trillion (US$120 billion), making it the single largest outlay for a government road construction scheme (as of March 2022).

[7] National Corridors Efficiency Program (NCEP) entails 5,000 km (3,100 mi) phase-I decongestion of 185 choke points by 34 6-8 laning, 45 bypasses and 30 ring roads of 6 NC.

[1][7] List of 44 economic corridors (EC):[1] Logistics parks entailing 45% of India's freight traffic have been identified to be connected by Bharatmala economic corridors (EC), to develop hub-and-spoke model where hub-to-hub transport can be done with 30 tonne trucks and hub-to-spoke transport can be done with 10 tonne trucks.

[1][13] North East Economic corridor will connect 7 state capitals and 7 multimodal waterways terminals on Brahmaputra on the bharatmala route (slide 21).

It will make current corridors more effective & will improve connectivity with north east and leverage synergy with inland waterways.
