Delhi Metro has started the preliminary works for the fifth metro bridge on Pink Line, connecting the existing Majlis Park station and Maujpur in north-east Delhi. The project is carried out under the Dehli Metro phase 4.
The bridge will be 560 metres long and will be constructed over the Yamuna river, crossed by four other metro bridges as part of the Pink Line. The bridge will connect the Soorghat metro station and the Sonia Vihar metro station of the Majlis Park –Maujpur corridor.
After carrying out geotechnical investigation at the location of proposed piers, the activity of casting of test piles is in progress.
This bridge will be constructed up between two existing bridges on Yamuna, the Wazirabad and the Signature bridges. This bridge crosses river Yamuna at about 385m downward of old Wazirabad bridge and 213m upstream of existing Signature bridge.
All approvals from the concerned agencies have been obtained for the construction of the bridge.
The design of the bridge was finalised using the Building Information Modeling (BIM) technology. With the help of this technology, a 3D model of the bridge was uploaded with intricate details of the proposed structure. For the completion of the Phase 4 designs, Delhi Metro’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 possible.
This will be the first ever metro bridge over Yamuna to be built using the Cantilever construction method, that is used when few spans ranging from 50 to 250m exist. 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. Employment of this technology will make the bridge look aesthetically better.
The fully elevated Maujpur -Majlis Park line (Pink Line) will be a 12.55-km long served by 8 stations, connecting northeast Delhi.
Under the phase 4 of Delhi metro three corridors totalling 39 km and 48 stations were approved.
