Kuwait is building one of the world’s longest causeways to its remote north where it will pump billions into “Silk City”, aiming to revive the ancient Silk Road trade route. The oil-rich emirate is eager to inject life into the uninhabited Subbiya region on its northern tip that has been chosen as the location for Silk City. The plan is to reinvigorate the ancient Silk Road trade route by establishing a major free trade zone linking the Gulf to central Asia and Europe. The 36-kilometre (22-mile) bridge, three-quarters of it over water, will cut the driving time between Kuwait City and Subbiya to 20-25 minutes from 90 minutes now. It is already nearly three-quarters completed. Despite the sharp drop in oil income which made up 95 percent of public revenues, the emirate has pledged to keep spending on capital projects almost intact.
