Why the Golden Gate Bridge Can Move Several Meters

Why can one of the world’s most famous bridges move by several metres without being unsafe? In this episode, we explore the engineering behind the Golden Gate Bridge and why controlled movement is essential to its survival. Discover how its deck, towers, cables, expansion joints, and suspension system respond to wind, traffic, temperature changes, and even earthquakes. We also look at the lessons engineers learned from bridge failures and why flexibility can sometimes be more important than extreme rigidity. It’s a fascinating look at structural movement, aeroelasticity, and the engineering principles that keep massive suspension bridges safe.
