DMRC Chief Mangu Singh said, "We are giving priority to this site in order to reduce rush at Rajiv Chowk station."
Beginning the construction was a big hurdle earlier as the site was located at a crowded location but most of the issues have been sorted out now, he said.
"We have started the work in October last year and within 17 months we have restored this road. Ninety per cent area of the road is open. Seventy per cent work has been completed in this corridor and our target is March 2014," Singh said.
