The Roads and Transport Authority (RTA) announced that construction of columns (piers) to support the viaducts and elevated stations along the Green Line is well on progress. Piers caps, weighting 46 tons each, will be erected on top of these piers using cranes and other special equipments.
Adnan Al Hammadi, Director of Rail Projects Construction Department from the Rail Agency, RTA said, "The number of piers to be constructed for the entire Green Line will be 535. Erection of the pier caps is in progress along Al Nahda and Jaddaf area, and will progress in due course throughout the city. The Green Line unlike the Red Line will pass through the Central Business Districts of Dubai."
"Like the Red Line, the concrete segments of the viaduct span will be erected using Launching Girders supported by the piers of Dubai Metro. As the casting of viaducts segments is nearing completion on the Red Line, the Launching Gantries working on the Red Line will be used on the Green Line. Eventually, these concrete segments will form the deck which is going to carry the Metro train and support the station platform and the rail tracks", he added.
The Metro project will call for 1700 spans in total to be constructed for both the lines with a total of 16500 deck segments, nine tower cranes, and 11 gantry cranes. The Red Line is 52.1 kilometers while the Green Line is shorter (22 kilometres) with a more localised route that focuses on two of Dubai's most densely populated areas - Deira and Bur Dubai. It is planned that the Green Line will run from Al Ittihad Square through Deira and Bur Dubai to Burjuman, through Health Care City to Jadaff in the South, and from Al Ittihad Square through Salahuddin Road to Al Qiyadah intersection toward Al-Qusais Area.
