The Gulf Cooperation Council (GCC) is planning to invest over $119.6bn in infrastructure projects, of which 90% will be diverted towards rail projects, according to a recent study.
The Business Monitor International study said the investments will be made over the next ten years, according to omanet.om.
Saudi Arabia will spend an estimated $25bn on the Saudi Landbridge project, the 450km Haramain high-speed railway and the North-South railway.
The UAE is also planning to invest $7.6bn in a 131km monorail track in Dubai that will mostly be underground.
The study also said that significant amounts are being invested in infrastructure projects in Kuwait, Bahrain and Qatar, notably the $4bn Qatar-Bahrain causeway.
The GCC will also propose a major rail project, estimated to cost around $25bn, and scheduled for completion in the next six years.
