The elevated viaduct of the underconstruction Janakpuri West – Botanical Garden corridor of the Delhi Metro will pass over the Delhi – Mumbai railway tracks as well as the Modi Mill flyover between the Okhla Phase 3 and Ishwar Nagar Metro stations.
Between these two Metro stations, which will be located at a distance of about one kilometre from each other, the Delhi Metro engineers are going to encounter two major construction related challenges, which are, crossing the ever busy Delhi – Mumbai railway corridor as well as the two important loops of the Modi Mill flyover.
For crossing the railway corridor, which consists of five tracks, DMRC is planning to install a steel bridge, as the installation of such a bridge will cause minimal disruption to the railway operations below. This bridge will cross the tracks at a height of about 17 metres. However, the requisite permissions for starting construction work over the railway lines is expected soon.
After crossing the railway tracks, the viaduct will also pass over two loops of the Modi Mill flyover which lead to the two sides of the Mathura Road below (towards Ashram and towards Badarpur). The construction work over both these crucial loops will be carried out without causing any disruption to the flow of traffic below.
While the length of the span crossing over the first loop towards Ashram will be 34 metres, the length of the span over the second loop towards Badarpur will be 37 metres. Segmental launching technology will be used for carrying out construction on this stretch. The viaduct will come up at both the locations at a height of 17 metres.
The construction work of this portion of the viaduct has already been started. While work on the construction of the piers near the flyover are almost over, the launching girder to be used for the launching of the segments has also started work about a fortnight back. The construction of the viaduct 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 the engineers for constructing the viaduct is also very narrow. Despite such space constraint, the Modi Mill flyover has been kept entirely available for traffic.
The Janakpuri West – Botanical Garden corridor of Delhi Metro’s Phase 3 is 36.5 kilometres long with 24 stations. The construction work of the entire corridor is currently in progress and the work is expected to be finished by the end of 2016.
