About 75% of civil work is done at seven underground stations — Rajendra Nagar, Moin-ul-Haq Stadium, Patna University, PMCH, Gandhi Maidan, Akashvani and Patna Junction — with several already in finishing work. A new tunnel boring machine was being deployed at Patna Junction, which will be a major interchange.
The Bhootnath–Malahi Pakri stretch and station are complete and have final approval from the Commissioner of Metro Rail Safety.
