In the first phase, five stations of Patna Metro will be operational by March 2025. Patna MRTS, constructed under a public-private partnership model, is estimated to cost ₹13,365.77 crore (US$1.5 billion). 

This cost excludes land acquisition cost, which will be paid for by the Bihar government. In January 2022, Larsen & Toubro (L&T) secured the order from metro operator Delhi Metro Rail Corporation (DMRC) for the design and construction of the Corridor-2 of Phase-1 of Patna Metro.[12] L&T classifies this contract, worth ₹1,989 crore (US$230 million), as a significant order. 

The major scope of work for the project comprises six underground metro stations: Rajendra Nagar, Moin-Ul-Haq Stadium, Patna Science College, Patna Medical College and Hospital, Gandhi Maidan and Akashvani of Corridor-2.
