The Mumbai Metro  is a rapid transit system being built in Mumbai, India’s largest city.

In June 2006, the Prime Minister of India, Dr. Manmohan Singh, laid the first stone for the first phase of the Mumbai Metro project, which comprises a three-line high-capacity metro railway system spanning 63 kilometres.

Phase I of the metro project will be implemented on a Build-Operate-Transfer basis for a 35-year period. The phase includes construction of three metro lines. A consortium led by Anil Dhirubhai Ambani Group’s Reliance Energy Ltd (REL) along with Veolia Transport Co. and with Mumbai Metropolitan Region Development Authority (MMRDA) secured the contract for the Indian Rupee symbol.svg2,356 crore (US$525.39 million) Versova-Andheri-Ghatkopar corridor.

Work has already begun on this line, which should be completed by 2012, with Simplex Infrastractures Ltd carrying out construction. The other corridors in the first phase include the 38-km Colaba-Mahim-Charkop route and the 14-km Bandra-Kurla-Mankhurd route. The cost of the project will be shared by the central and state governments.

The main objective of the Mumbai Metro is to provide rail-based mass transit services to people within an approach distance of 1 to 2 kilometres, and to serve the areas not connected by the existing Suburban Rail network. The Mumbai Metro is to be built in three phases, at a total cost of Indian Rupee symbol.svg36,000 crore (US$8.03 billion).
