Brooklyn Bridge: The First Steel‑Wire Suspension Bridge

Completed in 1883, the Brooklyn Bridge was the world's first steel‑wire suspension bridge. Its two massive stone towers support four main cables, each spun from thousands of galvanized steel wires—a revolutionary material at the time. The bridge spans 1,595.5 feet (486.3 m) across the East River, connecting Manhattan and Brooklyn. Designed by John A. Roebling and completed under the supervision of his son Washington Roebling and daughter‑in‑law Emily Warren Roebling, it remains an icon of 19th‑century engineering.
