Benjamin Franklin Bridge
When the bridge opened in 1926, its 1,750-foot main span made it the longest suspension bridge in the world. Paul Cret, architect of the Rodin Museum, was the designer. The bridge, which crosses the Delaware River, is mainly used by cars and the PATCO commuter train, which has several stops in Center City and South Jersey. The bridge is most impressive when it's lit at night. Start the 1¾-mile walk (one way) from either the Philadelphia side, two blocks north of the U.S. Mint, or the Camden, New Jersey, side, where there are metered parking lots. Enjoy stunning city views along the way, but know it's best to walk across on mornings or cooler days, as there's no shade.
