The King Fahd Causeway is a series of bridges and causeways connecting the city of Khobar in the Eastern Province of Saudi Arabia with the island nation of Bahrain. Spanning approximately 25 kilometers, the causeway stands as an impressive engineering feat and an important link for commerce and travel in the Persian Gulf region. Officially opened on November 26, 1986, the causeway was named after King Fahd bin Abdulaziz Al Saud of Saudi Arabia. It has greatly facilitated the flow of people and goods between the two countries, bolstering their economies and cultural exchanges. The causeway consists of four major segments, marine embankments, small bridges, and seven man-made islands that serve as interconnecting points and provide areas for border stations and other facilities. It is supported by approximately 7,000 concrete piles and includes a two-direction carriageway. It is one of the most significant transport infrastructures that represents a physical manifestation of the regional cooperation between Saudi Arabia and Bahrain.
