text: History The Hyderabad Metro rail project was approved by the Union government, in 2003. As Hyderabad continued to grow, the Multi-Modal Transport System (MMTS) had insufficient capacity for public transport, and the Union Ministry of Urban Development approved construction of the Hyderabad Metro rail project, directing the Delhi Metro Rail Corporation to conduct a survey of the proposed lines and to submit a Detailed Project Report (DPR). To meet rising public transport needs and mitigate growing road traffic in the twin cities of Hyderabad and Secunderabad, the state government and the South Central Railway jointly launched the MMTS in August 2005. The initial plan was for the Metro to connect with the existing MMTS to provide commuters with alternate modes of transport. Simultaneously, the proposals for taking up the construction of MMTS Phase II were also taken forward.
  In 2007, N. V. S. Reddy was appointed Managing Director of Hyderabad Metro Rail Limited, and the same year, Central Government approved financial assistance of  1639 crore under a Viability Gap Funding (VGF) scheme. The option of an underground metro system in Hyderabad was ruled out by L&T due to the presence of hard rocks, boulders and the topography of the soil in Hyderabad. Hyderabad Metro initially began under the Andhra Pradesh Municipal Tramways (Construction, Operation and Maintenance) Act, 2008 and later on, it came under the Central Metro Act which permitted revision of fares. On 26 March 2018, the Government of Telangana announced that it would set up an SPV "Hyderabad Airport Metro Limited (HAML)", jointly promoted by HMRL and HMDA, to extend the Blue line from Raidurg to Rajiv Gandhi International Airport, Shamshabad, under Phase II after the completion of Phase I in 2020.
  Initial bidding
  The bidding process was completed by July 2008 and awarded to Maytas, which failed to achieve financial closure for the project as per schedule by March 2009.
