Benjamin Franklin Bridge
Quick Summary
The Benjamin Franklin Bridge is a suspension bridge that spans the Delaware River, connecting Philadelphia, Pennsylvania, with Camden, New Jersey, in the United States. When completed in 1926, it held the record for the world's longest span at 525 meters (1,750 feet).1
The bridge was designed by Ralph Modjeski and is a steel suspension bridge that utilizes steel wire for its cables, a significant material in modern bridge construction that emerged with the Industrial Revolution. It represents an evolution in engineering, moving beyond earlier materials like wood and stone to incorporate the strength and possibilities of steel.1
