Bridge of the Horns

The Bridge of the Horns (, ) is a proposed construction project to build a bridge between the coasts of Djibouti and Yemen, across the Bab-el-Mandeb, between the Red Sea and Gulf of Aden. It would be constructed by Al Noor Holding Investment. In 2010, it was announced that Phase I had been delayed. In 2015, civil war broke out again in Yemen. As of July 2020, nothing more has been heard of the project.
Prospective structure.
The length of the bridge is estimated at , with a total cost of around USD20 billion. It was proposed by the Dubai-based firm Middle East Development LLC headed by Tarek Bin Laden. The opening date was expected to be in the year 2020.
To clear submarine and surface vessels, the proposed bridge would have the longest suspension span in the world measuring . The overall length of the entire bridge spanning the Red Sea, starting in Yemen, connecting to the island of Perim, and continuing on to Djibouti on the African continent, would be roughly . It would have to allow very large ships of the Suezmax size in both directions simultaneously.
It was anticipated that about 100,000 cars and 50,000 rail passengers would cross the bridge daily.
Expected use.
Twin cities, referred to as Al Noor City, would be built on either end of the bridge; the prospective site's developers indicate that they will run on renewable energy. On the Djibouti side, President Ismael Omar Guelleh granted to build Noor City, the first of the hundreds of "Cities of Light" which the Saudi Binladen Group envisions building. The developers state that they expect Noor City to have 2.5 million residents by 2025, and the Yemeni twin city to have 4.5 million, while they envision a new airport serving both cities at a capacity of 100 million passengers annually. A new highway connecting the cities to Dubai is proposed, though there are no plans for roads to connect sparsely populated Djibouti with the population centers of Addis Ababa in Ethiopia or Khartoum in Sudan. One of the uses that are imagined for this bridge is for easy transcontinental access to the Hajj in Mecca.
"The Economist" magazine, noting that developers state that the project will make Noor City the "financial, educational, and medical hub of Africa", commented, "Africans may wonder why the hub is not being built in a bit of Africa where more Africans live and which has food and water."
