The Sai Van Bridge is a cable-stayed bridge located in Macau, it was inaugurated on December 19, 2004. The bridge measures 2.2 km long and is the third one to cross the Praia Grande Bay connecting Taipa Island and Macau Peninsula on Hsiang-shan Island. It features a double-deck design, with an enclosed lower deck to be used in the event of strong typhoons when the other three bridges connecting Taipa and Macau Peninsula, both of which are single-deck, namely Ponte Governador Nobre de Carvalho and Ponte de Amizade, are closed. It is the world's first prestressed concrete double-deck main beam cable-stayed bridge and the world's largest-span double-deck concrete bridge. The lower deck of the bridge also carries the Macau Light Transit System, which started revenue operation almost nineteen years later on 8 December 2023.
