Top 10 Longest Bridges in the World

The history of developing bridge construction is closely linked with the history of human civilization. This is a list of the world’s top ten longest bridges more than two kilometers long sorted by the full length of their main spans above land or water. They are somehow wonders and landmarks on the earth as long as they exist all over the world. Suspension bridges have the longest spans according to the type of the bridge and they also vary in their designs. Bridges have always been an important part of our environment. They have been major subjects of literature and art, both ancient and modern. Wars have been fought over bridges and in many cases the capture of a strategic structure has a pronounced effect on the final outcome of the war.

10 Chesapeake Bay Bridge, United States

The Bay is the largest estuary in the United States and one of the largest in the world.  Its entrance is marked by the Chesapeake Bay Bridge Tunnel (CBBT).  The CBB, which is a dual-span bridge, is 4.316 miles (6.946 km) long and has four man made islands and thousands of concrete pilings to connect the Eastern Shore with the Western one.  This structure is one of the greatest fish magnets in the world, attracting and holding fish throughout all the seasons of the year. The Bay also has natural structures including grass beds, oyster bars, sand bars and deep water cuts over 200 feet deep. Add the man made structures like buoys, shipwrecks and artificial reefs and you have an incredible complex of fish habitats.
