@the.age.of.steel: The Brooklyn Bridge is basically a giant 19th-century flex. 🏗️ When it opened in 1883, its four enormous suspension cables were made from steel wire—an emerging material that allowed engineers to build higher, longer, and more impossibly than ever before. Thousands of miles of wire were twisted into cables strong enough to hold up the roadway, while the bridge’s massive stone towers anchored the whole thing. And this was only the beginning. 🗽 #brooklynbridge #nyc #History #pittsburgh #steel
