Why Aren't Africa and Europe Connected By A Bridge. Gibraltar Megaprojects. The initial primitive bridges just resembled logs thrown over water and didn't seem very secure. But as technology has advanced, societies have actually started to build truly impressive structures. The Dang Yang Kunshan viaduct, which holds the record for the world's longest bridge in the Guinness Book of World Records, is an excellent example.

There are locations, though, where bridges appear to be necessary but are absent. The Straits of Gibraltar is included in this. The Atlantic Ocean to the Mediterranean Sea is connected by this, which is significant globally. About 200 large ships passed through them every day. It's an essential route for Mediterranean communication with the outside world.

They became even more important after the official opening of the Suez Canal in 1869. The 100 miles long canal split Eurasia and Africa. And thanks to that, ships no longer needed to sail around Africa to get from the Indian Ocean to the Mediterranean and back.
