The Government of India has approved the Rs133.66bn ($1.88bn) Patna Metro Rail Project in the state of Bihar.
The project will comprise two corridors and is expected to be completed in five years.
In a statement, the government said that the metro system will offer an eco-friendly and convenient transportation alternative to the 2.6 million residents of the city.
The first metro rail corridor will stretch from Danapur to Mithapur, traversing through the densely populated areas of Raza Bazar, Secretariat, High Court and Law University Railway Station. The 16.94km corridor will feature three elevated and eight underground stations.
Around 11.2km of the Danapur to Mithapur corridor will be underground, while the remaining section will be elevated.
The length of the second corridor between Patna Station and New ISBT will be 14.45km, of which 9.9km will be elevated. It will comprise nine elevated and three underground stations.
Both corridors will have multimodal integration with railway stations and ISBT Station, as well as with bus, intermediate public transport (IPT) and non-motorised transport (NMT).
The Government of India finance minister Piyush Goyal said: “The residential areas along this metro rail corridors shall be immensely benefitted by this project, as the people of these areas will be able to travel on trains from their own neighbourhoods to reach different areas of the city conveniently.”
In December, the Indian laid foundation stones to build two metro lines in the city of Mumbai.
The two metro lines, Thane-Bhiwandi-Kalyan (Metro-5) and the Dahisar-Mira Bhayander (Metro-9), involve an investment of Rs150bn ($2.12bn).
