Concrete bridges are part of America’s past, along with its future, and without them, many commuters would be stranded getting to and from their destinations. Concrete is one of the longest lasting and durable building materials on the market. They’re used in everything from roadways to homes to buildings to bridges and everything in between. Concrete can take the punishment of impact, weather, and more. That’s why they’re used in bridges spanning from ocean to ocean.
Concrete bridges made an appearance in the early 1900s, when concrete became a primary building material among many markets. In the beginning, concrete bridge construction was small, across tiny bodies of water, such as lakes and rivers. In the beginning, these bridges were unsafe and most of them have been brought done due to incompatible construction methods that didn’t stand up to the test of time.
My how the times have changed. Concrete bridges, in some part, are often considered for any new bridge project, especially larger ones. Even if they aren’t used for the entire bridge, they’re used for a variety of aspects of the bridge, such as its foundation, especially where bodies of water are crossed. The Golden Gate Bridge, the Brooklyn Bridge, and other bridges across the nation have concrete as its base, with steel and other materials used to finish it out.
Without concrete, bridges would be under much more stress from day-to-day use. Concrete makes spectacular things possible, including bridges and should be considered for many projects, even if you think it may not be beneficial for it. Concrete bridges are just one testament to the power of concrete and how it’s integrated into our everyday lives. Concrete bridges are still a part of our future. As new bridges are developed and techniques get better, these bridges get stronger, still with a base of concrete.
