The city of Abu Dhabi is geographically located on the north-eastern part of the Persian Gulf in the Arabian Peninsula. It is on an island located less than 250 metres from the mainland and is joined to the mainland by the Maqta and Mussafah Bridges. A third bridge, designed by Zaha Hadid, is currently under construction. Abu Dhabi island is also connected to Saadiyat Island by a 5-lane motorway bridge. Al-Mafraq bridge connects the city to Reem Island and was completed in early 2011. Thhis is a multilayer interchange bridge and it has a total of 27 lanes which allow roughly 25 thousand automobiles to move per hour. There are three major bridges of the project, the largest has 8 lanes, four leaving Abu Dhabi city and four coming in.
Most of Abu Dhabi is located on the island itself, but it has many suburbs on the mainland for example: Khalifa City A,B and C, Al Raha Beach, Al Bahia City A,B and C, Al Shahama, Al Rahba, Between Two Bridges, Baniyas and Mussafah Residential.
Abu Dhabi has a hot arid climate. Sunny/blue skies can be expected throughout the year. The months of June through September are generally hot and humid with maximum temperatures averaging above 35 °C (95 °F). During this time, sandstorms also occur intermittently, in some cases reducing visibility down to a few meters.
The weather is cooler from November to March. This period also sees dense fog on some days. The oasis city of Al-Ain, about 150 km (93 mi) away, bordering Oman, regularly records the highest summer temperatures in the country; however, the dry desert air and cooler evenings make it a traditional retreat from the intense summer heat and year round humidity of the capital city
The density of Abu Dhabi varies, with high employment density in the central area, high residential densities in central downtown and lower densities in the suburbs. In the dense areas, most of the concentration is achieved with medium- and high-rise buildings. Abu Dhabi's skyscrapers such as the notable Abu Dhabi Investment Authority Tower, the National Bank of Abu Dhabi headquarters, the Hilton Hotel Tower and the Etisalat headquarters are usually found in the financial districts of Abu Dhabi. Other notable modern buildings include the Emirates Palace with its design inspired by Arab heritage, and thewww.visitabudhabi.com
The development of tall buildings has been encouraged in the Abu Dhabi Plan 2030, which will lead to the construction of many new skyscrapers over the next decade, particularly in the expansion of Abu Dhabi's central business district such as the new developments on Al Sowwah Island and Al Reem Island. Abu Dhabi already has a number of supertall skyscrapers under construction throughout the city.
