5. Hong Kong-Zhuhai-Macau Bridge

A 55-kilometer sea crossing structure connects three major cities, which are Hong Kong, Zhuhai, and Macau. The Hong Kong-Zhuhai-Macau Bridge (HZMB) is a large-scale infrastructure link in a seismically and typhoon-prone area. 

Its architectural design required continual changes during the early planning stages due to the region’s extreme environmental conditions.

This compelled architects and engineers to look into alternative materials, structural forms, and design solutions to ensure long-term stability and resilience. It also serves as a gateway to the Greater Bay Area, China’s fast-rising economic zone that includes nine more cities.

6. Trans-European Transport Network (TEN-T)

TEN-T is among the EU’s most ambitious and grand projects with the view of establishing seamless and sustainable transportation amongst the countries of the EU region. 

The project focuses on railway electrification, higher standard speeds, and integration of modern technology, improved ports and airports for a larger reach to remote countries.

Beyond reducing time and costs, its architectural plans focus on generating energy from renewable resources, improving urban travel, and using alternative fuels. 

This three-layered corridor architecture is set to be the backbone of Europe’s trade and travel.

7. Shanghai Tower

Located in Shanghai’s Pudong area, the Shanghai Tower is China’s tallest building with a height of 632 meters. 

Designers drew inspiration from traditional Chinese symbols such as the pagoda, bamboo shoot, and vase for the tower’s tapering and spiraling construction.

Curved glass panels wrap around the structure, helping to lessen wind loads and channel airflow around the building. Engineers reinforced the tower’s dynamic construction by building a core of nine cylindrical steel tubes connected by outriggers and diagonal bracing. 

This structural framework ensures stability against seismic pressures, resulting in a skyscraper that blends aesthetic appeal with engineered strength.
