The Strait of Gibraltar is the border between Africa and
Europe, only eight miles wide (13 km) at its narrows. In
Spain, to the left, the small spike of land is the Rock
of Gibraltar; Africa is on the right side of the image.
The blue Mediterranean opens up into the distance. The
proposed mega-project of a bridge or a tunnel, which is
being evaluated in stages, would link Europe with Africa
in the early 21st Century.
Here is a collection of links which present
ideas how to bridge the Strait of Gibraltar:
bridge designer T. Y. Lin, professor emeritus at the
University of California at Berkeley
and chairman of Lin Tung-Yen China Inc.
Lin's works include numerous spans as well as the roof
structure of the Moscone Convention Center in San
Francisco, the largest underground room in the world.
Among his unbuilt designs are a bridge from Alaska to
Siberia and a five-mile wide span over
the Straits of Gibraltar.

30 June-25 July 1997: The Secretary-General has
the honour to transmit to the Economic and Social
Council the report prepared in accordance with
Council resolution 1995/48 by the Executive
Secretaries of the Economic Commission for Europe
and the Economic Commission for Africa on the
work that has been done in connection with the
project to establish a
permanent link through the Strait of Gibraltar. The Economic and Social Council has
taken an interest in this project since 1982
following a decision by the Governments of
Morocco and Spain to carry out joint studies on
the feasibility of the project as part of an
agreement on bilateral cooperation adopted on 24
from ITA -April 1999: Under a bilateral
agreement, Spain and Morocco, through their
respective agencies S.N.E.D. and S.E.C.E.G, are
jointly studying the feasibility of a fixed link
across the Strait of Gibraltar, presently
developed as an undersea rail
discussion: The concept of a great global highway
that would connect five continents and more than
100 of the world's most important cities. This
proposed route extends from Scandinavia across
the Great Belt to Europe, then through the proposed tunnel at
Gibraltar to Africa, down the West Coast of
Africa, back up the East Coast, along the eastern
end of the Mediterranean, then from Istanbul to
Shanghai following the historic Silk Road path,
northward along the Siberian coast, through the
proposed tunnel under the Bering Strait, then
along the Pan American Highway and across North,
Central, and South America.

The Strait of Gibraltar as seen from the
Rock of Gibraltar was once one of the two classical
Pillars of Hercules, crowned with silver columns by
Phoenician mariners to mark the limits of safe navigation
for the ancient Mediterranean peoples. The rocky
promontory still commands the western entrance to the
Mediterranean Sea, separated from North Africa only by
the narrow Strait of Gibraltar. A British colony,
Gibraltar occupies a narrow strip of land at the
southernmost tip of the Iberian Peninsula. It is
separated from the Spanish mainland by a neutral zone
contained on a narrow, sandy isthmus. The rocky limestone
and shale ridge known as the Rock rises abruptly from the
sea, to a maximum elevation of 426 meters (1,398 feet).
Because of its strategic location and formidable
topography, Gibraltar serves mainly as a British fortress.
The Rock has traditionally been a symbol of British naval
strength. Most of its sparse land is taken up by air and
naval installations, and the civilian population is small.
