Metro to construct viaduct over railway line in Okhla

 The Delhi Metro will pass over the Delhi–Mumbai railway tracks as well as the Modi Mill flyover after the completion of Janakpuri West-Botanical Garden corridor under its phase 3 project.

The elevated viaduct, which will pass over the Modi Mill flyover between the Okhla Phase 3 and Ishwar Nagar Metro stations, is expected to be completed by October-end, said a Delhi Metro Rail Corporation spokesperson.

“Between these two Metro stations, which will be located at a distance of about one kilometre from each other, engineers are going to encounter challenges like crossing the ever busy Delhi-Mumbai railway corridor as well as the two important loops of the Modi Mill flyover,” he added.

“For crossing the railway corridor, which consists of five tracks, the 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, permissions for starting construction work over the railway lines is expected soon,” a DMRC official said.

According to DMRC, the construction work over two loops of the Modi Mill flyover which leads to Mathura Road will be carried out.

“While the length of the first loop towards Ashram will be 34 metres, the other loop towards Badarpur will be 37 metres. Segmental launching technology will be used for constructing the loop on the stretch. The viaduct will come up at both the locations at a height of 17 metres,” the official added.

The building 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,” he said.

The Janakpuri West-Botanical Garden corridor of Delhi Metro’s Phase 3 is of 36.5-kilometre with 24 stations. The laying of the entire corridor is
currently in progress and the work is expected to be finished by the end of 2016.
