This metro line will serve the Dubai Expo 2020 site, next to Al-Maktoum International Airport. It is understood that the link could be a standalone system, meaning that it could operate using different rolling stock and systems to the existing Green and Red Lines of the Dubai Metro network. There are four possible alignments running from an interchange station on the Red Line in the Jumeirah Lake Towers/Jebel Ali area up to the Expo site. The Route 2020 contains a 15km-long queue, of which 11.8km will be a raised segment and the staying 3.2km underground. Its course is intended to cover populated territories in the city to make compensation simple for the guests and the inhabitants of Dubai amid the half year world reasonable as well as later on. The 3.2km-long tunnel will be situated between Discovery Gardens and Green Community and will have profundity extending somewhere in the range of 12.5m and 36m. It is relied upon to be finished by December 2018. The Route 2020 arrangement likewise incorporates the development of three fundamental power supply stations and an extra footing force supply station.One solution that was earlier proposed was a line that would create options for stations at existing residential and industrial areas that are not currently on the metro network. That would run from the metro car park at Nakheel Harbour and Tower station, past Discovery Gardens, the Green Community, and Dubai Investment Park, before heading out to the Expo site next to the new airport. Another alignment that has been considered is an extension beyond Jebel Ali that will head inland to the Expo site. This solution would mean longer journey times to the Expo, and provide fewer opportunities to build new stations for existing centers of population and industry. Consultants are preparing to submit bids on April 14, 2014, for a contract to complete the preliminary engineering for this scheme.
