The construction of bridges has been a critical aspect of engineering for centuries, facilitating transportation and trade across rivers and valleys. Among the many innovations in bridge design, the introduction of steel as a primary construction material marked a significant turning point in engineering history. The first steel bridge ever built was the Eads Bridge, located in St. Louis, Missouri. Completed in 1874, this remarkable structure not only transformed transportation in the region but also set new standards for future bridge construction.

The history of bridge construction is a testament to human ingenuity and engineering prowess. Among the many milestones in this field, the advent of steel as a primary construction material marked a significant turning point. The first steel bridge ever built was the Eads Bridge, completed in 1874, which not only transformed the landscape of bridge engineering but also played a crucial role in connecting communities and facilitating commerce across the United States.
