As the U.S. celebrates its 250th anniversary, an iconic bridge marks a milestone of its own. In July 2026, the Benjamin Franklin Bridge connecting Philadelphia, Pennsylvania, and Camden, New Jersey, turns 100 years old. The chief engineer of the bridge was Polish-born Ralph Modjeski, founder of the firm now known as Modjeski and Masters. When the Benjamin Franklin Bridge opened in 1926, it was the longest suspension bridge in the world.
