Construction has been completed for the upgrade of the Sheikh Khalifa bin Zayed highway, which links the UAE with neighbouring Saudi Arabia. The project cost US$817 million and the work was carried out by the contractor, Abu Dhabi General Services Company (Musanada). The route runs 246km from the Mafraq region in Abu Dhabi to the border with Saudi Arabia. The road has been resurfaced and widened and now features three or four lanes, compared with the two lanes of the original route. The project included building 15 new interchanges, underpasses, service area, installing LED lighting and improving the drainage facilities.
