How Are Bridges Built?

As human beings started to expand across lands and territories, we needed a structure to overcome natural barriers and obstacles. Engineers harnessed their resources to create bridges, linking us between cities and changing the entire landscape.

How are bridges built? Bridge construction has undergone immense transformation since the beginning of times, including new sturdier materials, heavy machinery, and new construction techniques. Although building bridges is much easier in modern times, bridge engineering involves precise physics, vast resources, and thorough planning prior to and during construction.

Before bridges are constructed, planners must test the site for elements like the soil strength, depth, and layout of the land. Using computer-aided design, engineers can get a picture of the bridge’s behavior under different weights and weather conditions and determine the correct structure. After planning is complete, workers break ground on the job site, harnessing various materials and assembling structures to maintain support even under the pull of gravity.

While bridges require precise and careful work, the basic fundamentals to how bridges are strong are made to stand are simple once broken down. Find out the process of bridge building below.

Engineers invest a lot of time and resources to construct a bridge that achieves its purpose, facing similar challenges to those attempting to build underwater. Although there are different types of bridges, all of them employ engineering principles to act as standing structures that people use every day for transporting and commuting. Bridges are both functional in their purpose and elegant their in design, reflecting the harmony engineers and builders strive to achieve.
