Strait of Gibraltar Floating Bridge
August 29th, 2005
The last attempt at a bridge designed to span the Strait of Gibraltar was a design by U.S. engineer T.Y.Lin in 1986 which would require three support pylons one mile high and footings that plunge to the sea bottom one half mile down underwater and then sink an additional quarter of a mile destroying the existing ecology of the sea bottom surrounding it significantly disturbing the marine environment of the area. Lin’s design was based on previous traditional bridge concepts and was similar to the Golden Gate Bridge in San Francisco enlarged to five times its original size. Currently, the longest existing bridge is the Seto Ohashi Kojima bridge 13.22 kilometers long and built in 1988 for $8.3 billion dollars. It does not float.

Strait of Gibraltar
If you believe in climate change and then in an increase sea level then you could realize that what Strait of Gibraltar needs is something like a Dam that could make steady the Mediterranean sea level.
Maybe it would cost twice the Apollo program, but beaches, cities like Venice, Nile delta, La Manga and many things could be saved from the sea level increase.
More than 10 million people live in areas of the Nile delta that could be inundated by a 2 meter sea level rise.
The old mare nostrum maybe is one of the most polluted seas, but was the center of the world.
This inland sea is bordered on the north by Europe, the east by Asia, and in the south by Africa. This 969,100 sq. mile body of water is approximately 2,300 miles in length. Not mentioned Black Sea.
I Know a Dam is more expensive and even impossible to build (as channel Tunnel was) that an bridge or tunnel.
Also it will require make exclusas like Panama channel, but then it will make not necessary make an bridge maybe more than 150 feet over sea level to permit the vassels could pass under it
The level difference by consecuence of climate change could be used for hydro-electric power station. energy
It is necessary solve problems like salinity currents in the botton of the strait and sustain an Mediterranean live and living creatures that emigrate from one sea to the other
That way would make save The Mediterranean and join two continents, you could kill two birds with one stone.
Think Twice.
