Introduction

The United States is home to some of the most impressive and longest bridges in the world. These engineering marvels not only provide a vital transportation link between different regions but also serve as a testament to human ingenuity and perseverance. In this article, we will take a closer look at the 25 longest bridges in the United States, highlighting their lengths, locations, and interesting facts.

What Makes a Bridge Long?

A bridge is considered long if it spans a significant distance, typically exceeding 1,000 feet. The length of a bridge is determined by the distance between its two abutments, which are the structures that support the bridge at either end. The length of a bridge can be influenced by various factors, including the terrain, water depth, and the type of bridge.
