The Patna metro project is making significant progress, with work moving swiftly on the underground routes. Excavation of the Patna Metro Tunnel is currently underway at the Moin-ul-Haq Stadium, where two Tunnel Boring Machines (TBM) have been deployed to a depth of approximately 16 m. Construction of the underground metro line connecting Patna Junction and Rukanpura is set to commence simultaneously in July. The Patna Junction-Rukanpura segment of the subterranean metro will begin taking shape in the coming months, with construction slated to begin in July. Once soil testing is completed, a tender will be issued to select the agency responsible for the construction. The 32.497-kilometer metro project is expected to be completed by 2026.

The Patna Metro will consist of two corridors. Currently, construction is underway for Corridor One between Saguna Mod and Patliputra Railway Station, as well as from Mithapur to Khemnichal. For Corridor 2, work is in progress between Rajendra Nagar Terminal and Malahi Pakdi. In Corridor 1, the metro stations at Danapur, Saguna Mod, RPS Mod, Mithapur, Ramkrishna Nagar, Jaganpura, and Khemnichak will be elevated. In Corridor 2, the elevated stations will include Patliputra Bus Terminal, Zero Mile, Bhootnath Road, Khemnichak, and Malahi Pakdi. The majority of Patna Metro stations will be constructed underground rather than being elevated.

In Corridor 1, underground metro stations will be built at Patna Junction, Vidyut Bhawan, Vikas Bhawan, Zoo, Raja Bazar, and Rukanpura. In Corridor Two, the underground stations will be located at Patna Junction, Akashwani, Gandhi Maidan, PMCH, Patna University, Moin ul Haq Stadium, and Rajendra Nagar. The intersection of the two corridors will occur at Khemnichak and Patna Junction, serving as the interchange stations of the Patna metro.
