[1] The national highway still exists but its various segments have been assigned new numbers as stated in the following section.

The highway originated in Agra in Uttar Pradesh, generally travelled southwest through Dholpur in Rajasthan, Morena, Gwalior, Shivpuri, Guna, Biaora, Maksi, Dewas, Indore, Julwania & Sendhwa in Madhya Pradesh, and Shirpur, Nardana, Dhule, Malegaon, Nashik, Thane and terminated at Mumbai.

The stretch between Agra and Gwalior was marked as the North–South corridor/NH-44 by the National Highways Authority of India.

The road from Rau (Indore) to Mumbai has four lanes but the highway passed through congested Nasik city.

Now an elevated expressway of 25.27 kilometres (15.70 mi) has been built to solve the problem of congestion.
