Metro Link Express for Gandhinagar and Ahmedabad, abbreviated MEGA, is an under construction mass-transit rail system for the cities of Ahmedabad and Gandhinagar, Gujarat, India. The special purpose vehicle company was established in February 2010 and the Phase–1 of project was approved in October 2014 and is expected to complete by December 2018. The construction started on 14 March 2015.[1][2][3]

History[edit]

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's approval in the same year.[4][5] Following the estimated cost of Rs 4295 crores and the study of viability of project, it was abandoned 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.[6][7]

On 19 October 2014, Union Cabinet of India approved Rs 10773 crore for the Phase–1.[7] The Central government approved use of unused Western Railways land along the Botad- Sabarmati meter gauge line in November 2014.[8] The original plan of metro along Ashram Road was tweaked and the track was moved westward. The new plan added cost of Rs.500 crore and two more stations. It helped by fewer problems in land acquisition and less congestion on Ashram Road.[9][10] Mumbai-based J Kumar Infraprojects Ltd was allotted the construction of viaducts on the six kilometre-long route from Vastral to Apparel Park in February 2015 at cost of Rs 278.12 crore in 27 months.[2][3] In 2015 budget of Gujarat, Rs 611 crore was further allocated for project.[11] The ground breaking ceremony was held on 14 March 2015 for the construction of Vastral – Apparel Park route in presence of Gujarat Chief Minister, Anandiben Patel. The construction of this route is expected to complete by September 2016.[1] The work on north-south corridor is expected to start from July 2015.[12]

Proposed phases[edit]

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.

Controversy[edit]

Near Thaltej Gam on western side, 300-odd shop owners opposed the land acquisition while the officials said that there is need of huge land for depot and parking for the project.[14]

Former IAS officer and executive chairman of project Sanjay Gupta and seven of his subordinate officers were accused while two of them were arrested in May 2015 for alleged committed fraud of Rs 113 crore in procurement and use of ground filling materials for the project in 2012.[15][16]
