    The world’s longest cross-sea bridge, the 55-km-long Hong Kong-Zhuhai-Macao Bridge (HZMB), opened on Oct 24, 2018. The Guardian described it as one of the “seven wonders of the modern world”.

Construction（建筑工程）on the HZMB began in 2009 and cost about 120 billion（十亿）yuan. The bridge connects Hong Kong and Macao to the Chinese mainland city of Zhuhai, CGTN reported.

The HZMB is special in many ways. It’s designed to have a service life of 120 years, 20 years longer than most bridges.

And it’s not just a bridge，but also part tunnel（隧道）and part island. In one part, the bridge turns into a 6.7-km undersea tunnel that passes through two man-made islands. The tunnel is the world’s longest undersea tunnel for road traffic, allowing large ships to continue passing through the sea area above the tunnel.

The HZMB will make it much easier to travel between the three areas it connects. It will shorten the travel time from Hong Kong to Zhuhai from four hours to about 45 minutes.
