While Ferrogrão remains paralyzed for over a decade in Brazil, China erected the first central tower of the Hangzhou Bay bridge in January 2026. The structure will span 29.2 km over the sea.

As reported by CGTN, on January 16, 2026, engineers completed the topping out of the first main tower. The milestone was celebrated in Ningbo.

Indeed, when the work finishes in 2027, the maritime section will be the longest in the world for high-speed rail. Trains will travel at 350 km/h over Hangzhou Bay.

What makes the Hangzhou Bay bridge a world record

The bridge will cross 29.2 km over the sea — surpassing the previous world record for a trans-sea high-speed railway. No comparable structure currently exists in operation or under construction.

Likewise, it connects Haiyan, in Jiaxing county, to Qianwan New Area, in Ningbo. The route integrates three anchor cities of the delta: Shanghai, Hangzhou, and Ningbo.

29.2 km maritime extension — world record for high-speed railway
350 km/h projected speed — latest Chinese CRH standard
10-minute bay crossing — previously the road trip took over 1 hour
Over 1,000 submarine piles — foundation driven into the bed of Hangzhou Bay
Completion expected by 2027 — commercial operation soon after inspection

As reported by China Daily, over a thousand piles have been driven into the seabed. The project has involved Chinese state-owned construction companies for over 4 years.

The contrast with Ferrogrão and Transnordestina in Brazil

Brazil faces 3 major railway projects stalled or delayed for years. The Transnordestina faces paralysis and Ferrogrão remains without an environmental license since 2010.

Indeed, Ferrogrão has a projected 933 km route between Sinop (MT) and Itaituba (PA). The budgeted cost is R$ 25 billion, but the effective start never happened.

On the other hand, China delivers a high-speed railway section every 18 months on average, according to data from the Chinese Ministry of Transport compiled by CGTN.

As a result, the country already has over 50,000 km of high-speed lines in operation. It is the largest network of its kind in the world.

Likewise, projects such as the Jintang underwater tunnel in Zhoushan and the Lion Ocean Link bridge show a pattern of accelerated execution. Brazil does not have comparable speed.

How the Hangzhou Bay bridge was planned and why it took 4 years

The project was integrated into China’s five-year plan with national priority. It was treated as a strategic work for the Yangtze River Delta.

According to China Daily records, construction began in March 2023. The project was approved by China’s NDRC in 2022.

The winning design was signed by China Railway Major Bridge Engineering Group. The engineering had to circumvent the extreme tidal regime of Hangzhou Bay, which has the largest tidal variations in the world.

For this reason, the submarine piles have special structural reinforcement. Each was dimensioned to support high-speed trains and extreme phenomena.

Among them is the famous “tidal bore” — a giant wave that surges up the bay twice a day, a rare phenomenon on the planet.

Despite this, the original schedule was maintained at 4 years. Commercial delivery is expected in the second half of 2027.

Economic impact on the Yangtze River Delta and Chinese exports

The Yangtze River Delta concentrates about 24% of China’s GDP and is home to 3 of the world’s 10 largest port cities. The Hangzhou Bay bridge will reduce logistics time between them.

According to industry analysts, railway integration will accelerate the transport of high-value light cargo. Electronics and industrial machinery are the main beneficiaries.

Likewise, Chinese exports continue to break monthly records in 2026. Reducing internal logistics costs has a direct impact on global competitiveness.

As a result, Brazil may see indirect pressure on commodities exported to Asia. Soy, ore, and oil depend on Chinese ports for outflow.

Furthermore, Brazilian ships docking in Ningbo, Shanghai, and Zhoushan will benefit from faster railway exits.

According to port sector data, these three ports account for 40% of the volume of heavy commodities imported by China.

Likewise, Chinese capital invested in internal infrastructure frees up logistics flow on trans-Pacific routes. More cargo per day means less port congestion.

As a result, Brazilian exporters may see a marginal reduction in demurrage costs, a fee charged when ships are idle beyond the contracted period.

On the other hand, this depends on the overall pace of the Chinese economy. In a year of contraction, the effect quickly disappears.

What this means for Brazilian infrastructure

Brazil has the third largest railway potential in the world by extension, but operates only 28% of it. Most of the network has been deteriorated or abandoned since the 1990s.

On the other hand, new projects face environmental, land, and financing barriers. The bidding for sections like Ferrogrão and FIOL progresses slowly.

Thus, comparing the structure with Ferrogrão exposes structural differences. It’s not just money — it’s also institutional speed and political priority.

Caveats and what could still delay the bridge

However, the Chinese schedule depends on complex load tests. High-speed railway bridges require rigorous inspection before commercial operation.

Despite this, CRBC (China Railway Bridge Corporation) has a track record of on-time deliveries. The last major trans-sea bridge — Hong Kong-Zhuhai-Macau — was delivered in 2018.

However, minor structural problems may still appear during testing. The Hangzhou Bay bridge must undergo validation by CRRC and the Chinese regulator before receiving commercial trains.
