Dubai's Roads and Transport Authority (RTA) has said the Al Khail road widening and improvement project, one of the biggest projects currently undertaken by the RTA, is 90% complete in some stages, and the first half of this year would see the opening of key phases of the project, Wam has reported. The project acts as an extension of the Business Bay Crossing, and reflects RTA's efforts to open up auxiliary traffic corridors to Sheikh Zayed Road and Emirates Road; as these two roads account for a huge portion of the high traffic movement, said Mattar Al Tayer, head of the RTA. “Due to the massive nature of the project, RTA divided it into six phases and the work is currently underway in four phases costing about Dhs1.925bn in total,” he said.
