Benjamin Franklin Bridge

US has many busy and important bridges, after all there are great rivers as Hudson and Delaware for example. Here is an example from lovely Philadelphia. Doesn't happen very often that you can go under the bridge just like that, yet we often see how cars are racing under bridges in NYC.

The Benjamin Franklin Bridge — known informally as the Ben Franklin Bridge and originally named the Delaware River Bridge — is asuspension bridge across the Delaware River connecting Philadelphia, Pennsylvania, and Camden, New Jersey. Owned and operated by theDelaware River Port Authority, it is one of four primary vehicular bridges between Philadelphia and southern New Jersey, along with the Betsy Ross,Walt Whitman, and Tacony-Palmyra Bridges.

The chief engineer of the bridge was Polish-born Ralph Modjeski, its design engineer was Leon Moisseiff, and the supervising architect was Paul Philippe Cret. At its completion on July 1, 1926, its 1,750-foot (533-meter) span made it the world's longest suspension bridge span, a distinction it would hold until the opening of the Ambassador Bridge in 1929.
