Buenos Aires is preparing to shift its urban mobility strategy underground. The city government has initiated a public tender for the design, construction, and long-term operation of several estacionamientos subterráneos en plazas y parques de Buenos Aires, aiming to reduce surface-level congestion and reorganize how vehicles enter the city’s most crowded districts.
The initiative, formalized through Joint Resolution N.º 9/MJGGC/26 on April 6, 2026, establishes a 20-year public works concession. The primary goal is to create strategic parking nodes that discourage the indiscriminate flow of private cars into the central area, thereby improving general traffic circulation and reclaiming street space for pedestrians and public transit.
Unlike many large-scale municipal projects, this plan will not draw from the city’s public budget. The government has structured the project as a 100% private investment, allowing the city to expand its subterranean infrastructure without incurring immediate public debt. According to official project guidelines, the 20-year concession period was determined as the necessary window for private firms to amortize the high costs of deep-earth construction while maintaining state oversight.
Strategic locations and neighborhood impact
The current tender focuses on four specific high-traffic areas across the city. These sites were selected to act as buffers, capturing vehicles before they penetrate deeper into congested residential or commercial cores. The project stems from a private initiative submitted by the firm E-ARG SRL and has been declared of public interest by the Ministry of Economic Development.
| Location/Space | Neighborhood |
|---|---|
| Lavardén and Los Patos | Parque Patricios |
| Parque de Innovación | Núñez |
| Plaza Inmigrantes de Armenia | Palermo |
| Plaza Noruega | Belgrano |
Once completed, these facilities are expected to have a combined capacity of approximately 1,500 vehicles, though this figure may be adjusted based on the final engineering projects submitted by the winning bidders.
Beyond parking: A new urban model
The city is not viewing these sites as mere garages. The proposal integrates a multi-employ approach where the surface level is revalued. Most of the planned spaces will include complementary services, such as gastronomic offerings and entertainment areas, alongside the restoration and enhancement of the existing green spaces above.
By moving the parking underground, the government intends to increase local security and improve the overall quality of the public realm. The strategy is to transform these plazas from transit-heavy zones into community-centric hubs where the infrastructure supports the city’s needs without compromising the visual or environmental integrity of the parks.
To ensure these developments do not harm the local ecosystem, every project must undergo a rigorous Environmental Impact Evaluation under Law 123. No construction can initiate until the developers obtain the mandatory Certificado de Aptitud Ambiental (CAA), which verifies that the project meets the city’s sustainability and environmental standards.
Financial terms and legal framework
The financial viability of the project is anchored by a monthly base canon established by the Banco Ciudad, set at $95,596,312. The winning companies will be responsible for the entire lifecycle of the project: from initial design and construction to ongoing maintenance and commercial exploitation for the duration of the 20-year term.
The legal architecture of the concession is based on a combination of city regulations, specifically Laws 469 and 3.058, and will be implemented under the general concession regime of Law 6.246. The General Directorate of Concessions and Permits will serve as the primary regulatory body, with the power to administer the contracts, issue operational circulars, and apply penalties or rescind the concession if the private operator fails to meet the established terms.
Timeline and next steps for bidders
The city has already made the bidding documents available for free on the official government website. The window for submitting offers is narrow, closing on May 6 at 12:00 PM. The formal opening of the first envelope of bids is scheduled for 12:30 PM that same day at the headquarters of the General Directorate of Concessions and Permits, located at Avenida MartÃn GarcÃa 346.
Interested parties may coordinate site visits to the four designated locations via email, provided the request is made at least five days prior to the bid opening deadline.
The next critical milestone will be the opening of the bids on May 6, which will determine which private entities will lead the transformation of these urban spaces. Following the award, the projects will enter the environmental certification phase before any ground is broken.
