Brazil: BR-324 and BR-116 Highway Concession Auctions Await TCU Approval

The Bottom Line

• Federal government awaits TCU approval for new concession auctions of BR-324 and BR-116 highways.
• The projects are expected to attract approximately R$14 billion in new investments.
• New concessionaires will be selected via competitive bidding on the $B3SA3 stock exchange.

The Brazilian federal government is progressing with the process to define new concessionaires for the BR-324 and BR-116 highways in Bahia, following the departure of ViaBahia from their administration. Former Bahia Governor Rui Costa announced on May 9, 2026, that the auction process is pending final approval from the Federal Court of Accounts (TCU).

According to Costa, all necessary documentation has been submitted by the responsible agencies, and the determination of auction dates now hinges on the conclusion of the TCU's technical analysis. "All material has already left the Executive, has already left the Agency, and is now with the TCU, under analysis. As soon as the TCU releases it, the material will be forwarded and the auction date set," Costa stated. This procedural step underscores the rigorous oversight applied to large-scale infrastructure projects in Brazil, aiming to ensure transparency and fiscal responsibility before public tenders are launched.

Projected Investments and Economic Impact

During the interview, Rui Costa emphasized that the forthcoming contracts are expected to usher in a new phase of significant investments in Bahia's two primary federal highways. "The tender will define, on the São Paulo Stock Exchange ($B3SA3), the new company that will manage and invest approximately R$14 billion in the BR-324 and BR-116 Sul," he declared. This substantial capital injection is anticipated to stimulate regional economic activity, create employment opportunities, and enhance logistical efficiency for businesses operating in and through Bahia.

The R$14 billion investment figure highlights the federal government's commitment to modernizing critical transportation arteries. These funds are earmarked for a comprehensive scope of works, including road duplication, construction of additional lanes, pedestrian overpasses, and marginal roads. Furthermore, the projects entail the implementation of advanced monitoring and operational systems, which are crucial for enhancing traffic flow, safety, and overall connectivity. Such improvements are vital for reducing transportation costs, improving supply chain reliability, and supporting the growth of various sectors, from agriculture to manufacturing, that rely on efficient road networks.

Strategic Importance and Concession Model

Costa also indicated that one of the highway sections has a more advanced timeline, with further announcements anticipated in the coming days. The BR-324 and BR-116 concessions are integral to the federal government's new portfolio of concessions slated for 2026. This broader program reflects a strategic shift towards leveraging private sector capital and expertise for infrastructure development, a model that has gained traction in Brazil over recent decades. The auctions aim to select companies to assume administration of these stretches after ViaBahia's contract concludes, ensuring continuity and renewed investment.

The concession model typically involves long-term contracts where private entities are granted the right to operate, maintain, and expand infrastructure in exchange for collecting tolls or other user fees. This approach offloads the financial burden from the public budget while potentially introducing greater efficiency and innovation in project execution and management. For investors, these concessions represent long-term, stable revenue streams, often indexed to inflation, making them attractive assets, particularly for pension funds and large institutional investors. The competitive bidding process on $B3SA3 is designed to ensure that the most capable and financially robust operators are selected, maximizing the benefits for both users and the public treasury.

Regulatory Oversight and Future Outlook

The involvement of the TCU is a critical component of Brazil's infrastructure concession framework. As the federal audit court, the TCU plays a pivotal role in reviewing the legality, legitimacy, and economic viability of public contracts, including concessions. Its approval is a prerequisite for advancing the bidding process, serving as a safeguard against irregularities and ensuring that the terms of the concession agreements are fair and aligned with public interest. This oversight provides a layer of security for potential investors, signaling a commitment to a well-regulated environment.

The successful execution of these auctions and subsequent investments in the BR-324 and BR-116 highways could set a precedent for other planned infrastructure projects within the 2026 federal concession portfolio. It signals a continued push by the Brazilian government to attract private investment into critical sectors, aiming to bridge the country's infrastructure gap. The focus on modernizing key logistical corridors is expected to have a positive ripple effect on Brazil's overall economic competitiveness and its attractiveness as an investment destination. Market participants will closely monitor the TCU's decision and the subsequent bidding process for indications of broader trends in Brazilian infrastructure development and investment opportunities.
