How are bridges built?
I'd like to know how bridges are built.
Sure! Engineers typically begin by creating a plan for the bridge, including its design and location. Then they construct a foundation to support the bridge's structure, usually by driving piles into the ground or pouring concrete into drilled holes. From there, they build the superstructure, which consists of the piers, abutments, and span sections. Finally, they install the roadway and any necessary support systems like guardrails and lighting. Would you like me to explain any of these steps in more detail?
