When it comes to awe-inspiring bridges spanning over waterways, China's Hong Kong-Zhuhai-Macao Bridge (HZMB) and United States' San Francisco-Oakland Bay Bridge stand out as remarkable mega projects. The two bridges not only serve as vital transportation hubs but have also evolved into sought-after tourist destinations, attracting visitors from around the world to admire their views and grandeur.

With a span of 55 kilometers, the HZMB is one of the world's longest cross-sea bridges. It links China's special administrative regions of Hong Kong and Macao with Zhuhai in south China’s Guangdong Province. The bridge stands as testament to a remarkable engineering achievement, serving not only as a convenient transportation link but also as a breathtaking landmark.

The HZMB offers many attractive aspects to tourists. It seamlessly connects three distinct regions, allowing visitors to explore the diverse cultures, cuisines and attractions of Hong Kong, Macao and Zhuhai in a single day.

The San Francisco-Oakland Bay Bridge is an iconic landmark of the San Francisco Bay Area. This bridge connects San Francisco and Oakland, providing an ideal gateway for exploring the region. From the bridge, visitors are treated to stunning vistas of San Francisco's skyline, the charming city of Oakland and the picturesque bay – especially on clear, sunny days. Beyond its scenic charms, the San Francisco-Oakland Bay Bridge boasts a rich history, offering tourists an insight into the bridge's construction process and the stories that lie within its towering steel structure.

San Francisco and Oakland, both cultural and artistic hubs, surround the bridge with numerous museums, shopping centers, restaurants and entertainment venues, offering travelers ample opportunity to explore and experience the vibrancy of these cities.

The two bridges are not only the starting point for countless journeys, but they also offer a picturesque backdrop that showcases the engineering achievements and tourism appeal of these contrasting regions.
