The bridge is going to connect the Soorghat Metro Station and the Sonia Vihar Metro Station of the Majlis Park – Maujpur corridor. After carrying out a geotechnical investigation at the location of proposed piers, the activity of casting of test piles is in progress. The active course of Yamuna has been constructed by raising the level of the ground by filling of earth and sand from a nearby area with the protection of its slope through bamboo, jute netting and sandbags. The level of cofferdam has been kept the same as the level of the adjacent road to ensure smooth supply of construction materials.
This bridge will come up between two existing bridges on the Yamuna. These existing ones are Wazirabad Bridge and the Signature Bridge. If officials are to be believed, it is going to be first-ever Metro bridge over the Yamuna 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. Typically it extends from a flat, vertical surface such as a wall or pier, to which it must be firmly attached. Cantilever construction allows overhanging structures without additional support. This beautifies the look of a structure.
To finalize the Phase 4 designs, DMRC’s engineers are using the BIM platform, through which they have been able to finalise the designs even during the days of the pandemic when physical meetings weren’t possibleThis bridge crosses river Yamuna at about 385m downward of old Wazirabad Bridge and 213m upstream of existing Signature Bridge.
According to sources, mandatory approvals from the concerned agencies have been obtained for the construction of the bridge. DMRC is committed to fulfilling the conditions given by the Principal Committee on the Yamuna for construction of the bridge.
