The elevated Janakpuri (West)-Botanical Garden corridor of Delhi Metros Phase-III will pass over the railway tracks on which Delhi-Mumbai trains ply as well as the Modi Mill flyover between Okhla Phase-III and Ishwar Nagar Metro stations.
For crossing the railway corridor,which consists of five tracks,the DMRC is planning to construct a steel bridge to ensure minimum interruptions. This bridge will cross the tracks at a height of about 17m. The requisite permissions for starting construction work over the railway lines is expected soon, a DMRC spokesperson said.
The Metro corridor will also pass over two loops of the Modi Mill flyover,which lead towards Ashram and towards Badarpur on Mathura Road. While the length of the span crossing over the first loop towards Ashram will be 34m,the length of the span over the second loop towards Badarpur will be 37m. Segmental-launching technology will be used for carrying out construction on this stretch. The elevated Metro will come up at both the locations at a height of 17m, the spokesperson added. The construction of this portion has already started.
Meanwhile,construction of the pillars near the flyover is almost over. The construction of the elevated Metro corridor over these two loops of the Modi Mill flyover is expected to be completed by the end of October.
As the alignment of the corridor is passing along the Modi Mill flyover,the area available to engineers for construction is also very narrow. But the Modi Mill flyover has been kept entirely open for traffic, the spokesperson said.
The Janakpuri (West)-Botanical Garden corridor is 36.5 kilometres long with 24 stations. The construction of the entire corridor is currently in progress and the work is expected to be over by the end of 2016.
