In episode 2 of "Purposeless Assessments," we explore the surprisingly important gaps in bridges, known as expansion joints. These small separations in bridge structures might seem trivial, but they play a vital role in maintaining the integrity of bridges worldwide. Our host breaks down how these joints allow for the expansion and contraction of materials due to temperature changes, ensuring that bridges can withstand shifts in heat, cold, and even the vibrations of traffic. Without them, bridges would be more prone to cracks and costly damage.We also take a look at the history of expansion joints, dating back to early engineering solutions, and highlight some fun facts—like how skateboarders have repurposed these gaps for tricks or how advanced materials are evolving to keep bridges stronger than ever. Whether you’ve noticed these gaps while crossing a bridge or not, this episode uncovers the elegant simplicity behind them and why they’re crucial for the safety and longevity of our infrastructure.Got a bridge-related story or curious fact to share?
