This paper will describe more successful bridges built outside of North America. Many in North America feel that orthotropic steel decks are too challenging to design and offer little benefit to the owners of movable bridges. The advantages will be summarized. This is a continuation of the 2000 paper Existing Movable Bridges Utilizing Orthotropic Bridge Decks. Additional bridges from Europe and Asia are selected to demonstrate the complete range of all types such as the double swing bridge; the floating movable bridge; the skewed Bascule Bridge, and the double leaf bascule bridges, such as the Gateway to Europe Bridge in Spain. New ideas collected from www.orthotropic-bridge.org will be discussed. Key issues such as Dr.
