Buenos Aires City Hall opened a call for tenders on Monday for the specialised construction of the proposed 'F Line' of the capital's underground Subte transport network.
The F Line will run from Barracas, in the city's south to Palermo, in the city's north.
The assigned budget for the construction of the new line will is estimated at US$2 billion. It will have an extension of 12 kilometres and feature 13 stations, Infobae reported.
The government estimates that 600,000 passengers will use the F Line on a daily basis, in part given the fact that eight of the 13 lines will connect with other 'subte' lines and two will have access to other means of transport in Constitución and Palermo.
The stations will be named California, Súarez, Constitución (combining with the C Line), Entre Ríos (combining with the E Line), Independencia, Congreso (combining with the A Line), Corrientes (combining with the B Line), Córdoba (combining with the E Line), Las Heras, Hospital Rivadavia, Salguero, Plaza Italia (combining with the D Line) and Palermo.
The call for tender comes during a heated electoral year, though incumbent City Mayor Horacio Rodríguez Larreta faces no major threat to his leadership according to polls.
The construction of the Lines F, G and I - all currently inexistent - was sanctioned 18 years in 2001 ago by the City Legislature.
