World’s Longest Sea Bridge Opens in China: See the Video.

It took seven years but the world’s longest sea bridge is finally finished. Officially open today, the longest sea bridge in history links Hong Kong, Macau and mainland China so that a trip that could take up to 4 hours is now a mere 30 minutes.

A marvel of engineering, the Hong Kong-Zhuhai-Macao Bridge is 34 miles long including the underwater tunnel which is connected by two man-made Islands. (The tunnel is so cargo ships can pass by overhead.)

Check out the video to get an idea of the breathtaking feat.
