Delhi plans subway to link IGI Airport Metro and T2

29 Aug 2023 CW Team

The Delhi Metro Rail Corporation (DMRC) has announced its intention to build a subway that would establish a connection between the IGI Airport Metro station on the Airport Express line, which is positioned at Terminal 3 (T3) of the Indira Gandhi International airport, and Terminal 2 (T2). Currently, commuters utilising the Metro service from T2 are required to leave the IGI Airport Metro station and traverse a distance of approximately 500 metres alongside the road to gain access to the terminal.

According to sources familiar with the project, this gap will be significantly reduced to merely 70 metres with the implementation of the new subway.

The planned subway will possess a width of 10 metres and a height of 4.2 metres, and the projected cost for its construction is estimated at around Rs 260.60 million. They further explained that the chosen construction technique would involve the utilisation of the box pushing method, and the anticipated duration for completion is approximately 21 months following the awarding of the construction contract.

The construction approach, stating, "The method to be employed for building the subway is the box pushing method. This technique eliminates the need for extensive vertical excavation or large-scale digging. It is notable for its swifter pace in comparison to the traditional cut-and-cover technology commonly employed in subway construction projects. The decision to employ the box pushing method takes into account various factors including the presence of utilities, buildings, and other structures in the adjacent areas, along with the constraints posed by limited available space and concerns related to managing traffic."
