A bridge is being planned over the Red Sea to connect the Middle East with the African continent. The proposed bridge will cost around $23 billion. Stretching 17 miles, or 28 kilometers, it will include a six-lane motorway and a four-track railway, according to AFP. It is being proposed by Tariq Bin Laden, Al-Qaeda chief Osama Bin Laden's half brother who is a businessman in the construction industry. He has been lobbying the governments of Yemen and Djibouti, the two countries that will connect the bridge, to back the project. Such a bridge would create a direct link between the Middle East and Africa without having to pass through Saudi Arabia or travel by sea vessel. The bridge will facilitate African Muslims in reaching the holy city Mecca, in Saudi Arabia, for the Hajj, or annual pilgrimage. It will also create thousands of jobs and will be built alongside two cities at either side of it. Opponents of the project are concerned it will be built on an area prone to earthquakes and that it could damage business at Djibouti's port. Also, AFP reported that the bridge could provide easier access for terrorists seeking ways to reach impoverished and unstable countries in the Horn of Africa.
