After remaining under-construction for more than eight years,a section of the flyover,which comprises Wazirabads Signature Bridge,is expected to be ready by March.
One carriageway of the 1.5-km-long flyover on the Outer Ring Road covering four intersections at Timarpur,Nehru Vihar,Wazirabad and Mukherjee Nagar will be ready by the first week of March,said officials from Delhi Tourism and Transportation Development Corporation Limited (DTTDC). The carriageway will connect Mukarba Chowk to ISBT.
The opening is conditional to shifting of gas godowns in the area, an official said.
The project was announced in 2004 by Delhi government,and was to cost Rs 1,131 crore.
The flyover forms part of the Western approach to the Signature Bridge. The other carriageway,from ISBT to Mukarba Chowk,will be functional by May. On the Eastern approach,the flyover at Khajuri Khas Chowk in Northeast Delhi will be ready by November-end.
According to officials,the approaches have rib-shaped pre-cast segmental integral structures. This is to give the project a unique design. The concrete ramps have also been given a bamboo finish, said the official. The entire project is expected to be completed by December 2013.
The project was initiated with a plan of making this a landmark bridge,the surrounding areas are to be developed as tourist destinations. The project is divided into two parts,approaches and main bridge.
The work on the approaches started in June 2008. The approaches will be like multi-level grade separators with loops,ramps and rotaries, said an engineer from DTTDC.
The Eastern approaches are being constructed near Bhajanpura. It comprises of a 1.8-km-long embankment to connect the main bridge with Marginal Bund Road at Khajuri Khas intersection. A flyover will also be constructed comprising of ground-level rotaries at Khajuri Khas intersection. The flyover will end near Wazirabad and will help decongest the intersection, said an official from DTTDC.
On the Western approach,the flyover will be constructed along the Outer Ring Road. Loop and ramps will be constructed to connect main bridge with Outer Ring Road, said the official
The work on the bridge began in June 2010. The proposed bridge is being constructed across Yamuna,600 metres downstream from the existing barrage at Wazirabad.
The main bridge is a bow-shaped,cable-stay structure. The main deck of the bridge will be supported by cables,which in turn will be connected to a central pylon. The pylon is made of high-grade steel and is being manufactured in China. It will be shipped to India as asymmetrical blocks and assembled to make one structure.
The main bridge is 675-m long. The pylon will be 154 metres in height,taller than Qutab Minar, said the official.
