The Delhi Metro has already built four bridges across the Yamuna in the first three phases, including 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 but this will be the first bridge to be built using the cantilever construction method. A cantilever is a rigid structural element which extends horizontally and is supported at only one end. Cantilever construction allows the construction of overhanging structures without additional support structures.
