@architectzvideos: What you DON’T see is more impressive than what you do 👀 Beneath every cable-stayed bridge tower lies a hidden engineering marvel — massive pile foundations driven deep into the seabed, each one reinforced with steel cages and anchored into solid rock. This is what actually holds up thousands of tons of concrete and steel above the waves. Most people drive over bridges every day without ever knowing what’s happening 60+ feet below the surface. 🌊🏗️ Follow for more engineering deep-dives ⚙️ #CivilEngineering #MegaStructures #Engineering #Construction #HowItsMade
