MetroLink Express Gandhinagar and Ahmedabad route map

Metrolink Express for Gandhinagar and Ahmedabad (MEGA) is a proposed mass-transit rail system for the cities of Ahmedabad and Gandhinagar, India. The special purpose vehicle company was established in February 2010 and the Phase–1 of project was approved in October 2014.

History

In 2003, Gujarat Infrastructure Development Board carried out the study for urban transport between Gandhinagar and Ahmedabad. It also carried out the detailed project report through Delhi Metro Rail Corporation and RITES and submitted it in June 2005 and received Central Government approval the same year.[1][2] Following the estinated cost of Rs 4295 crores and the study of viability of project, it was abondoned in 2005 to give priority to the Ahmedabad BRTS and Regional Rail system Projects. In 2008, considering the future developments in and around Ahmedabad and Gandhinagar, the project was revived and new corridors were designed to make the project viable.

The special purpose vehicle company, Metro Link Express for Gandhinagar and Ahmedabad (MEGA) Company Ltd, was established by Government of Gujarat on 4 February 2010 with Rs 200 crore. Later in 2014, it was decided that the Central Government will own 50% of the company.[3][4]

On 19 October 2014, Union Cabinet of India approved Rs 10773 crore for the Phase–1.[4]

Corridors

    • East-West corridor: 20.54 km
  • Corridor:
    • Elevated: 28.2 km
    • Underground: 7.0 km

Proposed phases

Phase-I extension, Phase-II, Phase-III will include connection to Sardar Vallabhbhai Patel International Airport to the MEGA network through Motera. The services to Gandhinagar, GIFT City, etc. will be extended from Motera towards North. Also, other parts of the city that have been left as of now e.g. Civil Hospital, etc. will be connected. Most probably, if commissioned, the proposed Fedara International Airport, Dholera SIR, etc. will be connected to MEGA too, which will be after 10 years from now.
