You must see the Tsing Ma Bridge if a trip to Hong Kong is on the cards. It links the city to the Hong Kong International Airport in addition to being a 4,518-foot suspension bridge. Said another way, it is impossible to miss.

The bridge, which is 135 feet wide, took about $1.3 billion to build. Tsing Ma was constructed to support both rail and road traffic, in contrast to many other costly bridges. A small fortune in potential shipping revenue was wasted since the bridge was not built high enough for all ships to pass under due to a design error.
