Describes the construction of the 25-km King Fahd Causeway in the Arabian Gulf. On the basis of a review of the performance of marine structures elsewhere in the world, the paper outlines the salient features of concrete deterioration in sea water and discusses the durability requirements for concrete construction in marine environment. Concrete durability considerations for the causeway are outlined in selection of concrete materials and mixes. The durability monitoring of the causeway is being carried out in two phases. Phase I involves continuous visual inspection of the structure, and Phase II includes long term investigations on concrete specimens exposed to submerged, tidal, and atmospheric zones of the Arabian Gulf.
