The Patna Metro project hit another achievement, as TBM-04 completed the tunnel from Moin-ul-Haq Stadium Metro Station to Rajendra Nagar Metro Station. This signals the 7th tunnel breakthrough on Line 2 of the Patna Metro project.
TBM-04 successfully completed the excavation of approximately 681 metres of downline tunnel between Moin-ul-Haq Stadium Metro Station and Rajendra Nagar Metro Station. This progress was described as one of the most technically challenging components of the project by the officials.
The construction on the downline tunnel by TBM-04 is a part of the 6 underground stations planned for corridor II of the Patna metro project. It was reported that this section will be connected to Malahi Pakri metro station through a ramp of approximately 750 metres connecting the elevated section to the underground alignment.
Alongside this development, TBM-03 is moving at a steady pace in parallel, constructing the upline tunnel. The TBM is working on the remaining section of the tunnel and can reach Rajendra Nagar Metro Station by the end of June 2026.
The event was witnessed by Shri Sandeep Kumar R. Pudkalkatti, IAS (Secretary, UDHD-cum-Managing Director, Patna Metro Rail Corporation), along with several senior officials associated with the project.
Patna Metro Blue Line consists of 12 stations, featuring 6 underground and 6 elevated stations, spanning 16.2 km from Patna Junction to Patliputra Bus Terminal (New ISBT). Currently a 3.45 km elevated stretch between Pataliputra Bus Terminal and Bhootnath station on the North-South corridor is operational and approval to run metro services up to Malahi Pakri was recently given after safety inspections on this route.
Detailed Review Meeting
On 8th June, 2026, a detailed review meeting was chaired by Shri Sandeep Kumar R. Pudakalkatti, IAS ( Secretary, UDHD-cum-MD, PMRCL). Senior officials from PMRCL, DMRC, and concerned agencies participated in the review. Construction progress across various project corridors was assessed, and all critical bottlenecks were discussed in the meeting.
