New Delhi, Jul 24 (UNI) In December next year, the Delhi Metro Rail Corporation will add another first to its list of achievements, when it finishes construction on the Yamuna Depot-Anand Vihar section in East Delhi.
Under construction by the DMRC on the 6.17 km section in East Delhi are two of the longest spans of phase two of 70 m, which lie consecutively over the Karkardooma Flyover on the busy Vikas Marg in East Delhi.
''This will also become the highest point in the Metro system with the height of the platform being 19 m above the ground, making it the highest platform on the entire Delhi Metro Rail once it becomes operational,'' DMRC spokesperson Anuj Dyal said.
The 19 m high platform was necessitated by the need to build the Metro line while avoiding the vehicular traffic flow at Vikas Marg, one of the busiest intersections of the city.
''The height of the platform is so much here because there is already a road flyover there and DMRC has provided an elevation of 6.1 m above the Karkardooma flyover making the height of the platform from the ground level approximately 19 m. Thus, this point will be the highest in the Metro system,'' Mr Dyal said.
The normal height of a Metro platform is usually 12 to 13 m from the ground level and the maximum height at present is 17 m at Raja Garden on Line III in West Delhi.
The two 70 m spans are located between the Preet Vihar and Karkardooma Metro Stations. The first span crosses the Flyover and a ramp which is adjacent to the flyover, while the second crosses the drain.
Usually, the normal length of a special span varies from 40 m to 60 m while normal spans are 18 to 37 m.
These spans are being made using a special engineering method known as the Balanced Cantilever Method so as to avoid disturbance to the traffic during construction.
These spans are a part of the Metro line that is being constructed from the Yamuna Depot to the Anand Vihar (ISBT). The section is completely elevated and is 6.17 kms with a total of 5 stations namely; Laxmi Nagar, Nirman Vihar, Preet Vihar, Karkardooma and Anand Vihar (ISBT). The section is expected to open around December 2009 and is expected to increase the commuter traffic tremendously because of connectivity to the bus terminus. This section is further being extended upto Vaishali by 2.5 kms via Kaushambi.
