<p>The New Storstrøm Bridge in Denmark includes a signature main bridge located centrally at the bridge crossing, spanning over two ship navigation channels as a cable-stayed bridge. It spans over 2 x 160 m with a single, architecturally shaped pylon with an integral, monolithic connection centrally between the deck and the pylon. The central pylon provides vertical support to the deck through the stay cables and lower pylon, but also acts structurally as the point of longitudinal fixity for one of the three frames of the bridge. The paper will describe the key design challenges for the structural design of the cable-stayed bridge of the New Storstrøm Bridge, including a discussion on the pylon design, stay cables, stay anchorage concepts and the bridge structural system.</p>
