  Dubai International Airport became the busiest airport in the world by international passenger traffic in 2014, overtaking London Heathrow. Abu Dhabi International Airport is the second-largest airport in the UAE. Due to the announced expansion of Al Maktoum Airport on 28 April 2024, Dubai International Airport will be shut down once Al Maktoum Airport expansion will be completed.
  
  Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, and Ras Al Khaimah are connected by the E11 highway, which is the longest road in the UAE. In Dubai, in addition to the Dubai Metro, The Dubai Tram and Palm Jumeirah Monorail also connect specific parts of the city. There is also a bus, taxi, abra (traditional boat), and water taxi network run by RTA. T1, a double-decker tram system in Downtown Dubai, were operational from 2015 to 2019.
  
  Salik, meaning "open" or "clear", is Dubai's electronic toll collection system that was launched in July 2007 and is part of Dubai's traffic congestion management system. Each time one passes through a Salik tolling point, a toll is deducted from the drivers' prepaid toll account using advanced Radio Frequency Identification (RFID) technology. There are four Salik tolling points placed in strategic locations in Dubai: at Al Maktoum Bridge, Al Garhoud Bridge, and along Sheikh Zayed Road at Al Safa and Al Barsha.
  
  A 1,200 km (750 mi) country-wide railway is under construction which will connect all the major cities and ports. The Dubai Metro is the first urban train network in the Arabian Peninsula.
  
  The major ports of the United Arab Emirates are Khalifa Port, Zayed Port, Port Jebel Ali, Port Rashid, Port Khalid, Port Saeed, and Port Khor Fakkan. The Emirates are increasingly developing their logistics and ports in order to participate in trade between Europe and China or Africa. For this purpose, ports are being rapidly expanded and investments are being made in their technology.
  
  The Emirates have historically been and currently still are part of the Maritime Silk Road that runs from the Chinese coast to the south via the southern tip of India to Mombasa, from there through the Red Sea via the Suez Canal to the Mediterranean, there to the Upper Adriatic region and the northern Italian hub of Trieste with its rail connections to Central Europe, Eastern Europe, and the North Sea.
