Pragati Maidan Bridge
Indraprastha - Barakhamba Road-Dwarka (from Delhi metro line 3), 32.1 km long, is mainly built on viaduct, which makes the metro line architecturally unique in India. The Barakhamba Road-Indraprastha section includes the first Extradosed bridge in India which is also the second one of its kind in the world built over a railway crossing.
The viaduct, being constructed above 5 railway lines, without any interruption to their traffic. The DMRC, SYSTRA and the Indian Railways imposed very strict safety standards to ensure that no incident would happen and interrupt the daily traffic of more than 200 trains.
