Metro Phase III to go over rail tracks, flyover

September 2, 2013


NEW DELHI: DMRC, in Phase III, will attempt to construct over a railway line as well as two loops of a flyover. The elevated corridor (or viaduct) of the under-construction Janakpuri West-Botanical Garden section of Delhi Metro will pass over the Delhi-Mumbai railway tracks as well as the Modi Mill flyover. The flyover is located between the turning to Okhla Phase III and Ishwar Nagar Metro stations.The challenge, says Delhi Metro spokesman Anuj Dayal, is the acute lack of space for construction at this location. “Between these two Metro stations, which will be located about 1km from each other, our engineers are going to encounter two major construction-related challenges: crossing the busy Delhi-Mumbai railway corridor and the two important loops of the Modi Mill flyover,” said Dayal.

The DMRC is planning to install a steel bridge to cross the railway corridor, which has five tracks. “The installation of a steel bridge will cause minimal disruption to the railway operations below. This bridge will cross the tracks at a height of about 17m,” said Dayal, adding that the Delhi Metro is still awaiting permissions for starting the construction over the railway lines.

After crossing the rail tracks, the viaduct will pass over two loops of the Modi Mill flyover which lead to the two sides of the Mathura Road below — towards Ashram and Badarpur. “The construction work over both these crucial loops will be carried out without causing any disruption to the traffic below,” said Dayal. While the length of the span crossing over the first loop towards Ashram will be 34m, the length over the second loop towards Badarpur will be 37m.

“The construction of this portion of the viaduct has already started. This stretch of the viaduct — over the two loops of the Modi Mill flyover — is expected to be completed by the end of October,” Dayal added.
