Paris has the Eiffel Tower; New York has the Empire State Building; in Rotterdam it's the Erasmus bridge. Its structural scale and design articulation has become a distinctive landmark within the surrounding skyline. This cable-stay bridge links the northern and southern parts of the city with a 802 m span in spectacular style. The bridge deck is supported by steel cables slung over a single pylon that is bent to counter the forces of tension. Traffic passes underneath the 139 m pylon as it straddles the roadway. The structure is called "the Swan" by locals because of its graceful posture over the water. The Erasmus Bridge is such a dramatic departure in bridge building that it has even become part of the city's official logo. The top part of pylon of the bridge is reachable through an internal staircase.
