Arguably the longest bridge is the Bang Na Expressway, in Bangkok, Thailand. It is 33.5 miles long (54 km), but is not considered a bridge because it does not cross a single body of water, instead crossing a river and canals.

The longest bridge running over a single body of water in the world is now the Jiaozhou Bay Bridge in China. 42km in length, it links China's eastern port city of Qingdao to the island of Huangdao. The bridge cost over $1.4 billion to build and was completed in mid-2011.

Other record-holding bridges:

The longest bridge in the world for many years was the 36km-long Hangzou Bay Bridge, which opened in May 2008. The record-breaking bridge has main cable-stayed spans of 448m and 318m.

The world's longest bridge used to be the Confederation Bridge. It connects the Canadian province of Prince Edward Island to the province of New Brunswick. The 12.9 kilometre long bridge was the world's longest road bridge, crossing ice-covered water. It was opened to traffic in 1997.

The longest suspension bridge in Japan and the world is the Akashi-Kaikyo Bridge, completed in 1998 at a length of 1,991 metres.

The world's longest footbridge is believed to be the the Capilano Suspension Bridge, which crosses the Capilano River in Vancouver, British Columbia, Canada. This footbridge is 136m or 446 feet in length, with a height of 70m (230 feet) above the canyon.
