There will be twelve underground stations on the stretch, which will be part of Aerocity Line

NEW DELHI: Delhi Metro Rail Corporation ( DMRC ) has floated tenders for the design and construction of the 5.5km elevated section of the 20km Aerocity-Tughlaqabad corridor of its Phase IV project.

There will be four elevated stations on the corridor — Sangam Vihar, Khanpur, Ambedkar Nagar and Saket G Block — and 12 underground stops, the tenders for which is yet to be floated.

As part of this unique construction, a first-of-its-kind three-layer transport facility has been planned for the Mehrauli Badarpur Road in south Delhi. The stretch will see a 2.4km double-deck viaduct with a Delhi Metro corridor running on the upper deck and a six-lane flyover on the lower one, while a six-lane underpass connecting Saket G Block to Sangam Vihar will run below.

A DMRC spokesperson explained that the upper deck would come up at an elevation of 18m, while the flyover will be at height of 9.3m. The total length of the proposed integrated structure will be 2.4km.

“The flyover will start just after the proposed Sangam Vihar metro station and end after Ambedkar Nagar stop. It will also provide connectivity from Mehrauli Badarpur Road to BRT corridor,” he said.

A 430m six-lane underpass will be constructed at Saket G Block at Mandir Marg crossing. “This will provide uninterrupted traffic movement from Sangam Vihar to Saket-G Block towards Mehrauli from Badarpur and vice versa,” he said. The Saket-G station will be an interchange stop between Aerocity-Tughlaqabad and proposed Lajpat Nagar-Saket G Block corridors.

Delhi Metro is constructing a double deck viaduct on the Majlis Park-Maujpur corridor as well, which is expected to come up between Bhajanpura and Yamuna Vihar metro stations. “Currently, there are no such viaducts on the Delhi metro network,” the spokesperson said.

DMRC had earlier floated tenders for the 12.58km Majlis Park-Maujpur metro corridor, which has eight elevated stations.
