جسر الملك فهد
The King Fahd Causeway that connects Saudi Arabia to the island of Bahrain was inaugurated on 26 November 1986. It consists of five bridges linked by otherwise solid embankments and the design was chosen to try to minimize the environmental impact. Another causeway, the Qatar–Bahrain Causeway, is planned to link Bahrain to Qatar. This one will be solid for about half its length and the other half will be bridge. The presence of the causeway is likely to have a considerable effect on the circulation of water in the Gulf.
