NEW DELHI (Metro Rail News): The Delhi Metro Rail Corporation (DMRC) has commenced work on a fifth bridge over the Yamuna river that will connect the Soorghat Metro station and the Sonia Vihar Metro station. It is the part of phase four expansion of the Pink Line, which will see the corridor extending from Majlis Park to Maujpur, officials said on Tuesday. The bridge is being built between two existing bridges that are Wazirabad bridge and Signature bridge.
“The total length of the bridge is 560 metres… Pile foundation work is near completion and approximately 50% of sub-structure has been completed. The construction of superstructure by balanced cantilever technique has also been started,” said Anuj Dayal, principal executive director, corporate communications, DMRC.
The Delhi Metro has already constructed four bridges across the Yamuna in the first three phases which include the Yamuna Bank Bridge on the Blue Line, a bridge at Nizamuddin for the Pink Line, a bridge at Kalindi Kunj for the Magenta Line and one at Shastri Park for the Red Line. The new bridge will cross the Yamuna at around 385 metres downstream of the old Wazirabad Bridge and 213 metres upstream of the existing Signature Bridge.
This bridge will be the first to be built using the cantilever construction method, the officials informed.
“A cantilever is a rigid structural element which extends horizontally and is supported at only one end. Cantilever construction allows construction of overhanging structures without additional support structures. Employment of this technology will make the bridge aesthetically better,” said Dayal. “A 3D design of the bridge was also finalised using Building Information Modelling (BIM) technology'” he added.
