The detailed project report (DPR) for Phase I, comprising the Purple and Green Lines, of Namma Metro project was prepared by the Delhi Metro Rail Corporation (DMRC) and submitted to the BMRCL in May 2003. The final approval on a scheme that incorporated the expertise of DMRC and RITES Limited did not come until April 2006. The DPR prepared by DMRC envisaged a 33 km (21 mi) elevated and underground rail network with 32 stations for Phase I of the project. The proposed gauge was standard gauge unlike the broad gauge on the Delhi Metro network. The rationale for the metro includes reduced journey times, cutting fuel use, accident reduction and lower pollution.

Construction work for Phase I of the Namma Metro project was scheduled to start in 2005 but was delayed by a February 2006 change of government in Karnataka and continued debate over whether the project was financially feasible and appropriate for the city. Finally, on 25 April 2006 the Indian Cabinet approved the project, which was then budgeted at more than ₹54 billion (US$800 million). The cost escalated to ₹116.09 billion (US$1.7 billion) as various problems delayed the completion. BMRCL received ₹7 billion (US$100 million) from Housing and Urban Development Corporation (HUDCO), ₹250 million (US$3.7 million) from the Asian Development Bank (ADB), 23% from the Central Government, 33% from the State Government and the rest as a ₹49.05 billion (US$730 million) loan from the Japan International Cooperation Agency (JICA).

The foundation stone for the Phase I construction was laid by Prime Minister Manmohan Singh on 24 June 2006. Construction on Reach 3 and 3A of Phase I of the Namma Metro began in 2009-10. The total cost of the project on this stretch was ₹2,100 crore. The underground work commenced in May 2011. Each corridor consists of two tunnels which are the first underground tunnels built for trains in South India. The tunnels, dug using tunnel boring machines (TBM), are located approximately 60 feet below ground level, have a diameter of 5.5metres and are 5metres apart. Four TBMs, nicknamed Helen (TBM 1), Margarita (TBM 2), Kaveri (TBM 3) and Krishna, were used for tunnelling work on the Green Line. A trial run was conducted on 8 August 2013.

Construction of the stretch required 1.3 lakh tonnes of concrete, 44,500 tonnes of steel bars, and 190 km of high tension wires weighing 2900 tonnes. A total of 395 piers, including station piers and portals, were constructed on the stretch. The tallest pier of the viaduct is a 21-metre pier between Kuvempu Road and Sriramapuram stations, opposite Gayatri Devi Park. There 353 spans on the stretch, the longest being the 66 metre curved span over the railway track off Sriramapuram. The total roofing area of the 10 stations on the stretch was 47,000 square metres.

The line was opened to the public on 1 March 2014. BMRCL Managing Director Pradeep Singh Kharola stated that about 25,000 passengers travelled on the line on opening day. Civil works had not been completed at Peenya Industry and Peenya stations, among others. These were covered up by paintings, and work was expected to be complete in another two months. In the first month of operations, 7.62 lakh people at an average of 24,605 people daily used the line, generating a revenue of ₹1.5 crore (US$220,000).
