THE XXI CENTURY TRASPORTS LINK BETWEEN EUROPE AND AFRICA Italy, bridge across Mediterranean Sea
Great buildings in the past and present time YESTERDAY • “To connect the oceans” (Panama, Suez) • Powerful states, owners of powerful fleets • Through “parallels” • The courses to East TODAY • To connect the “Countries” • Also through “meridians” Gibraltar and Mazara two borderlands of Europe
THE STRAIT OF MESSINA BRIDGE • Link between Italian regions and/or hinge between two continents ? • It will promote the change of goods transport from road to railway
SUBMARINE TUNNELS Existing tunnels • Sei-Kan Tunnel (Japan) • Eurotunnel (France –England) • Tokyo Bay (Aqualine) Tunnel (Japan) Future tunnels • Tsushima-Kaikyo (strait) and Korean strait • Gibraltar (Morocco-Spain) • Bering Strait (Russia-USA)
SEI –KAN • 53.850 m length, existing from 1988 section

EUROTUNNEL • section
EUROTUNNEL • Upgrading works (Stratford-Dover, in progress)
TOKYO BAY- TUNNEL • Profile
TOKYO BAY- TUNNEL • Bridge and artificial island Kase–no-to
TOKYO BAY- TUNNEL • Humi - Hotaru artificial island and bridge
GIBRALTAR TUNNEL • PLAN
GIBRALTAR TUNNEL PLAN AND SECTION
GIBRALTAR TUNNEL • PROFILE
BERING TUNNEL • Russia – USA and two Diomede’s islands
KOREA - JAPAN TUNNEL • in project 120 km length, 5 islands
ARTIFICIAL ISLANDS • Channel of Sicily, is it possible to build a 130 km long tunnel ? • Artificial islands, Japanese experience, environment damage or benefit ?
REALIZATION • Heads and islands • TBM machines • Scheme and performances
RESULTS IN THE TIME • Why only goods and services ECONOMIC CONSEQUENCES • Building yard time • North Africa productions, quality and quantity changes • Removal of industries • Increase of people’s incomes and fundamental consumptions
STAGES • Research and feasibility project • Constituting Consortia and finding investors • Technical project and work planning • Tunnel heads, islands and links realization • Drilling phase • Realization of systems and plants
Technical data and performances of the Sicily – Tunisia tunnel -Total length 150 km. -Submarineportion length 136 km. - Two galleries (one for each way) with 7.6 m diameter, and a 45 m distance between them. - Gallery of exploration/service 4.8 m diameter in central position between the transit galleries. - Practicable total bypass connections every 375m. - Aerodynamic bypass every 200m. -Electric supply at the ends linked with national Tunisian/Italian power nets. At least two power stations at the artificial islands.
PHASES OF CONSTRUCTION The realization of the tunnel, by analogy with similar works, is divided in 4 phases at least: - Geologic research and executive project, planning and commissioning (for a period of about 4 years). The works for the construction of the tunnel include three phases (for an estimable length of about 7 years): - Positioning of 4 platforms for the building of artificial islands (well technique) and beginning of the realization of the heads (Pizzolato and Cape Bon terminals). - digging of the different portions of the tunnel (5 long sections) and building of artificial islands. - installation of all the technical plants (ventilation systems, drain systems …)
