Here’s the first half of the world’s soon-to-be longest water crossing, before it was built and now half way there, via NASA Earth Observatory:

If you want to get from Macau or Zhuhai to Hong Kong, you either have to take a boat or drive at least four hours (200 kilometers) across southeastern China. An ambitious engineering project intends to shorten that drive time to 40 minutes.

The HKZM connector will include roughly 42 kilometers (26 miles) of bridges over water, with another 7 kilometers (4 miles) passing through a submarine tunnel. The estimated $132 billion (Hong Kong) project will include three cable-stayed bridges and long stretches of causeways; the longest bridge section will be 29.6 kilometers (18.4 miles) long. Three lanes of traffic will move in each direction, roughly east-west across the water. Once completed, the Hong Kong-Zhuhai-Macau Bridge will be one of the longest water crossings in the world, equivalent to about 15 Golden Gate Bridges.
