Feats of Engineering series: The Hong Kong-Zhuhai-Macau Bridge

Reddy Kancharla has always been fascinated with engineering and construction, even now, decades after he first entered the fields. As a tribute to engineers and construction teams all over the world, he has begun a series of blogs called the "Feats of Engineering" that features the most jaw-dropping engineering marvels in history.

For this blog, Reddy Kancharla highlights the spotlight on the world’s longest sea bridge, the Hong-Zhuhai-Macau Bridge (HZMB).

While the HZMB was an ambitious project which was planned decades ago (in 1983 to be exact), it was only fairly recently that the technology to complete it was developed. The construction team started planning the project in 2004 and working on it in 2009.

One of the reasons it took a long time to complete was because two artificial islands had to be created to make building the bridge possible. These two artificial islands would be the entry and exit points of the underwater tunnel, which is a significant part of the bridge.

The bridge is 20 times longer the famed Golden Gate Bridge of San Francisco and cost over 120 billion yuan. The HZMB has proven to be quite the asset of infrastructure in the regions of Hong Kong and Macau, making travel easier between the two regions and offering a cheaper alternative to ferries.

Reddy Kancharla has extensive knowledge of engineering theories, principles, and practical solutions of engineering problems relating to civil engineering and the construction industry, and the development of quality systems in the construction industry per various codes and standards.
