Delhi Metro Rail Corporation has started work on the 12.5-km long elevated corridor being constructed over the Shinghali Bridge at Gujjar chowk. It will connect two ends of the existing Pink line, thus creating Delhi’s first ring corridor and is likely to be completed by next year. The viaduct will be 14 metres above the ground and the distance between the flyover and the viaduct will be six metres.
The corridor connecting Majlis Park to Maujpur corridor, part of its Phase-IV expansion, will pass over a double-carriageway flyover near north Delhi’s Jagatpur village. The elevated viaduct of this corridor will cross a flyover at Gujjar Chowk. Crossing flyovers is always a critical engineering challenge as the process needs meticulous planning and round-the-clock observation. The viaduct above the double-carriageway flyover is 34 meters long and T-girders will be installed above the flyover. Since it is a very busy flyover, the girder launch will be carried out during the late hours to avoid inconvenience to vehicular movement underneath. These specially designed T-girders will be precast in the casting yard and will be launched using high-capacity cranes.
