The extension corridor was scheduled to become operational by December 2020 but the construction work got delayed due to the Covid-19 pandemic and the resultant lockdowns with the new deadline for operation was May 2021.

The tunneling work for the underground corridor is carrying out using two methods, the 700 meters of tunneling was done using TBM (Tunnel Boring Machine), a contract for which was originally awarded to the joint venture of Shanghai Tunnel Engineering Co. Ltd. and SUCG Infrastructure India Pvt. Ltd in October 2017 which also includes construction of Dhansa Stand Metro station and for another 290 meters, tunneling work is being done by the cut and cover method, the contract for which was awarded to Paras Railtech Pvt. Ltd. in October 2020.
