Just about a month after TBM- Gomti (UP line) reached Hazratganj , the second TBM working on Down line has also reached below the MG Marg in Hazratganj. The total length of the 5.8m dia tunnel from Sachivalaya underground metro station to Hazratganj underground metro station on Down line is 783 m, out of which only 38 m now remains to be completed.

The tunneling in this stretch posed enormous technical challenge for LMRC officials as the route passes beneath some highly congested areas, old dilapidated buildings and close to basements of some prominent shops. Extensive instrumentation was therefore planned throughout the underground stretch and continuous online and real time monitoring was done by a team of dedicated experts to ensure safety of workmen and structures during TBM operation. Strict alignment control was maintained during tunneling operation through state of the art onboard computerized tunnel guidance system.

LMRC officials have expressed their appreciation and gratitude for the residents and shopkeepers of Hazratganj area for their extremely encouraging support for the tunneling project.
