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
