Connecting the kingdom of Saudi Arabia to the tiny island nation of Bahrain, the King Fahd Causeway is a marvel of modern engineering. This 25-kilometer-long series of bridges and causeways spans the Persian Gulf, revolutionizing trade and tourism between the two nations. With a ceremony fit for a king, the causeway was officially inaugurated on November 25, 1986, marking a new era of cooperation and economic growth for the region.
