A major extension to the green line is under consideration to link Dubai World Central, which will contain the new Jebel Ali airport, with Dubai International Airport through Dubailand, and a smaller extension running through the Lagoons in Ras al-Khor and Al-Jadaf. An extension of the red line is also being considered connecting to Palm Jebel Ali and Dubai Waterfront. At the same time, four new lines are planned: a purple line serving Business Bay, Burj Dubai and the creek extension; an orange line serving Dubailand; and a yellow line running along Al-Qudra road serving the Bawadi development.
The most advanced new line is the blue line. The RTA is preparing tender documents for consultants for the line, which will run alongside Emirates road, and will link Dubai International Airport and Jebel Ali Airport. The scheme is scheduled for completion in 2011. Australia's Bovis Lend Lease with Hong Kong's Mass Transit Railway Corporation (MTRC) is providing project management services to the RTA on Dubai metro (MEED 21:4:06).
