The design for the six-lane Ruby flyover, which promises to ease daily commute along EM Bypass, is almost ready. The highlight of the `6-bn elevated corridor is the 5.5-m skywalk planned below the upcoming Hemanta Mukherjee Metro station at the Ruby crossing. It will take three years to build the flyover. The implementing agency for the city’s highest flyover is the Kolkata Metropolitan Development Authority. Railway consultancy RITES has already submitted the draft DPR to KMDA. Contact: Kamalesh Basak, Chief Engineer, Kolkata Metropolitan Development Authority.Address: DJ-11, SCC-II, Salt Lake, Kolkata-700 091, 3rd Floor, Administrative Block. Mobile: (0) 94330 85040.Website: www.kmdaonline.org
