In its Phase III, the Delhi Metro Rail Corporation (DMRC) will attempt to construct the line over a railway line as well as two loops of a flyover, situated between the turning to Okhla Phase III and Ishwar Nagar Metro stations.
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.
DMRC says that there is acute lack of space for construction at this location.
Between these two Metro stations, which will be located about 1 km from each other, the DMRC 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. The DMRC is planning to install a steel bridge to cross the railway corridor, which has five tracks.
