Top 10 Longest Bridges in the US

The dictionary defines a bridge as: ‘A structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle.’

Millions and millions of dollars and countless hours of labor go into creating some of these enormous beasts. All structures are built for very specific purposes. To us, bridges are like useful works of art. The longest bridges in the US are all over the country and you might even encounter them on a daily basis if you live nearby. While many bridges are quite impressive in length, these top ten are longer than anything else you’ll drive across in the U.S.

Here are the top 10 longest bridges in the US that are breathtaking…

Completed in 1912, it was known as the “Eighth Wonder of the World” when it was first built.  In the beginning, people thought that attempting to build something so ambitious over miles of open water and a soft bottom in a harsh tropical climate seemed a bit crazy back then.

Finished in 1982, the longest bridge in the Florida Keys is wide enough to give a motorist room to pull over to change a flat tire and steal many glances at the perfectly green water.
