Saadiyat Island
The city of Abu Dhabi is on the southeastern side of the Arabian Peninsula, adjoining the Persian Gulf. It is on an island less than from the mainland and is joined to the mainland by the Maqta and Mussafah Bridges. A third, Sheikh Zayed Bridge, designed by Zaha Hadid, opened in late 2010. Abu Dhabi Island is also connected to Saadiyat Island by a five-lane motorway bridge. Al-Mafraq bridge connects the city to Reem Island and was completed in early 2011. This is a multi-layer interchange bridge and it has 27 lanes which allow roughly 25,000 automobiles to move per hour. There are three major bridges in the project, the largest has eight lanes, four leaving Abu Dhabi city and four coming in.
