Such positive impacts are mentioned in a sustainability strategy covering all phases of the causeway, from the design over construction and operation to decommissioning. The first of its kind in the GulfThe sustainability strategy is thought to be the first of its kind for a large-scale infrastructure project in the Gulf, and the strategy takes into account all three aspects of the sustainability concept: environment, social conditions and economics. Cradle to cradle as inspirationThe sustainability strategy is greatly influenced by the cradle-to-cradle philosophy, which is about designing products in a closed technological or biological system, so that they can be turned into something else at the end of their lives, thereby providing fuel for new products and eliminating waste.
Exploiting natural resourcesOne of the suggestions in COWI's sustainability report focuses on exploiting solar and wind energy. The consortium behind the construction of the bridge suggests establishing solar and wind power plants to produce energy to cover at least parts of the required power amount during construction of the bridge in addition to what will be needed later during operation of the bridge.
When the bridge is completed, extra wind and solar energy can be distributed to the local energy network providing an input to reduce the two countries' CO2 emissions, which are presently among the world's largest per capita. Other suggestions include the establishment of a desalination plant partially powered by renewable energy, a reed bed waste water treatment plant with reuse of nutrients as soil conditioner and the construction of artificial reefs to create favourable conditions for the area's marine flora and fauna.

The causeway will be constructed as a motorway with two lanes in each direction in addition to civil structures for a dual rail line.
The connection will consist of 15 kilometres of embankments where the water is shallow and 25 kilometres of bridge across the deeper water.
The connection will also feature two main arch bridges, each with a main span of 280 metres.
