Buenos Aires Launches Subway Line F Tender Alongside Major Road and Rail Upgrades

Buenos Aires launched a public tender for Subway Line F this week, a 9.8 km project with 12 stations backed by a USD 1.35 billion investment. The line represents the first new subway route in 25 years and is expected to begin construction in 2026.

Subway Line F Tender

The tender process advances plans to add capacity to the existing network. Officials have positioned the project as a direct response to long-standing demand for improved east-west connectivity across central districts. The 9.8 km alignment and 12 stations will link previously unserved areas once work begins next year.

Belgrano South Rail Improvements

Parallel work continues on the Belgrano South commuter route. Argentina secured a USD 75 million loan from the French Development Agency to fund electrification and track-doubling. Five underpasses valued at 3.7 billion pesos are already under construction between Laferrere and Gonzalez Catan stations to replace level crossings and ease road congestion.

Paseo del Bajo Road Corridor

Further north, the Paseo del Bajo project has received a USD 400 million loan from CAF. The 7 km roadway corridor runs between Puerto Madero and Retiro with a total project cost of USD 700 million. The investment targets north-south traffic flow through the city's core.

These developments build on existing commitments to modernise rail and road links. Construction timelines for the underpasses and the CAF-funded roadway sections are already in motion, while the Subway Line F tender sets the stage for bidding and contractor selection in the months ahead.

Next steps include finalising bids for Subway Line F and completing the remaining underpass works on the Belgrano South line. Progress on the Paseo del Bajo corridor will depend on disbursement of the CAF loan and ongoing site preparation between Puerto Madero and Retiro.
