@engmhd_: 🚗 Ever wondered why many highway bridges are hollow inside? 🤯 It might look like engineers are using less concrete—but that's exactly the point. The hidden box girder design makes bridges: 🏗️ Lighter 💪 Stronger 🌪️ More resistant to twisting 💰 More efficient to build over long distances Sometimes, the strongest structures aren't solid—they're intelligently designed. 💬 Did you know highway overpasses are hollow? Tell us before watching! 📌 Save this reel for later. 📤 Share it with someone who loves engineering. 👷 Follow for more engineering stories. #CivilEngineering #StructuralEngineering #BridgeEngineering #BoxGirder #BridgeDesign
