With Line 1 already in operation and the construction of Line 2 nearing completion, Lima's metro is shaping up to be one of the most important infrastructure projects in the region.

Having a mass rapid transit system to serve the city of Lima has been a dream for decades: the first proposals were formulated back in the 1970s but the actual construction of the megaproject was abandoned because of the deep economic and social crisis that affected the South American country in the 1980s.

Everything changed in 2009, when a consortium led by Graña y Montero and Norberto Odebrecht was awarded the construction of the line, a USD410.2 million project (with Corporación Andina de Fomento playing a crucial role, as it granted a loan of USD300 million). The megaproject included nine new stations and installation of new electromechanical equipment for the entire route. The final cost of the project was estimated to be around USD549 million.

The metropolitan railway system that serves the capital city of Peru provides an efficient solution that connects different areas (barrios) within the 8-million-inhabitant city. Line 1 started its operations in 2012 and in 2014 the second phase of the project was successfully completed, with an addition of a 12.5km segment to the existing line.

“Lima was lagging behind for a long time," Manuel Wu Rocha, CEO of GyM Ferrovias, told TBY. “More than 9 to 10 million people in Lima lacked access to a metro network, so it has been a big change for the city. Our main challenge was teaching Lima's citizens how to use a new system of transport with a pre-paid card and metro stations, and integrate it into their daily lives. One of the major challenges was to teach users that they can plan their trip in advance, and organize their life accordingly and know exactly how long it will take to travel."
March 2014 marks the expansion of Metro de Lima. A 30-year concession contract of USD5.36 billion was awarded by a consortium headed by ACS and FCC; the two companies are in charge not only of the design but also of the construction of Line 2. The consortium includes leading international companies with extensive experience in the construction sector: Salini-Impregilo, Cosapi, Ansaldo Breda, and Ansaldo STS. According to the master plan presented by the consortium, the 5km Line 2 is expected to be fully operational by end-2017.
In September 2015, the World Bank approved the USD300 million financing plan for the construction of the new line. According to the World Bank's official website the new system will move around 2.3 million inhabitants that live in the peripheral barrios of the Peruvian capital.

Due to its size and the economic impact that the new line will have on the city, Metro de Lima is shaping up to be one of the main projects in the entire South American region. The local Minister of Transport is confident that the project will foster the growth of the economic activity of Lima, a city that historically has been characterized by undisciplined growth combined with a lack of modern transportation systems.

The majority of Limeños are forced to move within the city using traditional transit solutions including 31,000 buses, microbuses, and vans with an average age of 15 to 20 years, and taxi and moto-taxis running 560 routes lacking dedicated lanes, terminals, or adequate stops. This abundance of vehicles creates constant traffic that obstructs the main arterial roads of Lima, carrying significant operational costs for the local municipalities, uncontrolled levels of pollution, and tragic traffic accidents.

The new system will connect the barrio of Ate Vitarte with the city center and Callao on the Pacific. The first section of Line 2 is expected to open in 2017 with the remaining three sections to be completed by 2021.
