China Builds South America's Longest Sea Bridge in Brazil 2026

China is building South America's longest sea bridge, a 12.4-kilometer structure in Brazil's Bahia state that will connect Salvador to Itaparica Island and slash travel times for millions. The project, officially launched on July 1 by President Luiz Inácio Lula da Silva, marks one of the continent's most ambitious public works and underscores China's growing role in Latin American infrastructure.

The bridge, known as the Salvador-Itaparica Bridge System, will carry four lanes of traffic across the Bay of All Saints, linking the capital of Bahia with the Baixo Sul region. Beyond the record-breaking length, the bridge promises to cut two hours from the journey for commuters and businesses alike.

What the Salvador-Itaparica Bridge Includes

The project is more than just a bridge. According to the Bahia state government, the full system comprises several integrated components that together form a comprehensive mobility solution. The centerpiece is the 12.4-kilometer sea crossing, which features a 682-meter cable-stayed main span rising 85 meters above the water to allow large ships to pass.

But the system also includes 4.4 kilometers of new road accesses in Salvador, a 22-kilometer expressway on Itaparica Island that will bypass the urban core, and the duplication of 8 kilometers of the BA-001 highway between Tairu and the Funil Bridge. These additions ensure the bridge connects seamlessly with existing infrastructure.

• 12.4 km total sea crossing – the longest in South America
• 682-meter cable-stayed main span with 85 meters of vertical clearance
• 4.4 km of new urban accesses in Salvador
• 22 km expressway on Itaparica Island
• 8 km highway duplication on BA-001
• Estimated 10 million beneficiaries across 250 municipalities

Why the Bridge Matters for Bahia and Brazil

The bridge is expected to benefit around 10 million people living in nearly 250 municipalities surrounding the Bay of All Saints. For residents of Itaparica and the Baixo Sul, the current journey to Salvador requires a ferry or a long detour around the bay, often taking hours. The bridge will reduce that to minutes.

Economically, the link is designed to integrate the region's logistics, boosting tourism and facilitating the movement of goods. The high clearance for ships ensures that port operations in Salvador—a major commercial hub—remain unaffected. This balance between connectivity and maritime traffic was a key engineering challenge.

The project also aligns with Brazil's broader push to modernize its infrastructure and attract foreign investment. China's involvement in the construction, though not detailed in the source, reflects its strategy of exporting engineering expertise and capital to emerging markets.

China's Role in Latin American Infrastructure

China has become a major player in infrastructure projects across Latin America, from ports to railways. The Salvador-Itaparica Bridge adds to this portfolio and signals China's willingness to take on complex, high-profile ventures. For Brazil, partnering with China offers access to financing and technical know-how that might otherwise be unavailable.

However, such collaborations also raise questions about debt sustainability and geopolitical influence. While the source does not specify the financing terms, these are issues that analysts will watch closely as the project progresses.

What to Watch Next

Construction is expected to take several years, and the project will face engineering, environmental, and financial hurdles. The bridge's impact on local ecosystems in the Bay of All Saints will be scrutinized, as will its economic returns. For now, the groundbreaking represents a milestone in South American infrastructure and a testament to China's expanding global footprint.

As the project advances, stakeholders will look for transparency in costs and timelines. The promise of reduced travel times and economic integration is significant, but delivering on that promise will require careful execution.
