New Delhi:
The DMRC has commenced initial paintings at the development of the 5th metro bridge over the river Yamuna as a part of its Segment-IV paintings at the Majlis Park-Maujpur hall, officers mentioned on Sunday.
The brand new 560-metre-long bridge will arise between two present bridges at the Yamuna i.e. Wazirabad Bridge and the Signature Bridge. It’ll be the first-ever metro bridge over the Yamuna to be constructed the use of cantilever development method, they mentioned.

The bridge, with 8 spans and 9 piers, will attach Soorghat metro station and Sonia Vihar metro station of the Purple Line.
“After wearing out geo-technical investigation on the location of proposed piers, the process of casting of check piles is in development,” The Delhi Metro Rail Company (DMRC) mentioned in a commentary.
Recently, there are 4 bridges of Delhi Metro at the river Yamuna, viz, at Yamuna Financial institution (698.eight m on Blue Line), Nizamuddin (602.eight m on Purple Line), Kalindi Kunj (574 m on Magenta Line), and Shastri Park (553 m on Purple Line), it mentioned.
To utilise the to be had time all the way through this monsoon season, a cofferdam has been built, clear of the lively process the Yamuna, by way of elevating the extent of the bottom by way of filling of earth and sand with coverage of its slope thru bamboo, jute netting and sand luggage, the officers mentioned.
The extent of the cofferdam has been stored similar as that of the adjoining street to verify provide of considered necessary development subject matter like metal reinforcement, steel liner, able combine concrete and so forth, they mentioned.
“This would be the first-ever metro bridge over Yamuna to be constructed the use of the cantilever development approach. A cantilever is a inflexible structural component which extends horizontally and is supported at just one finish,” the commentary mentioned.
Most often, it extends from a flat, vertical floor comparable to a wall or a pier, to which it will have to be firmly connected. Cantilever development permits overhanging buildings with out further toughen. Employment of this generation will make the bridge glance aesthetically higher, the DMRC mentioned.
The design of the bridge was once finalised the use of the “Development Knowledge Modelling” (BIM) generation. With the assistance of this generation, a 3-D type of the bridge was once uploaded with intricate main points of the proposed construction.
For the finalisation of the Segment-IV designs, DMRC engineers are the use of the BIM platform, wherein they have got been ready to finalise the designs even all the way through the times of the pandemic when bodily conferences were not imaginable, the officers mentioned.
This new bridge will move river Yamuna at about 385 m downstream of outdated Wazirabad Bridge and 213 m upstream of the present Signature Bridge, the DMRC mentioned.
“All obligatory approvals from the businesses involved had been received for the development of the bridge. The DMRC is dedicated to fulfil the stipulations given by way of Primary Committee on Yamuna for development of the bridge,” the commentary mentioned.
More than a few eco-friendly measures will probably be taken all the way through its development.
All of the development actions are being performed with minimal impact at the floodplains.
Recovery of the floodplain that can be impacted by way of the development of bridge alignment or pillars in it’s going to be undertaken, the DMRC mentioned.
The muck and particles generated can be disposed of scientifically and no dumping will be allowed at the floodplains, it added.
