World's highest bridge opened
Paris - The world's highest bridge, designed by
British architect Norman Foster, was opened in
south-western France dec,2004, taking its first
traffic over the river Tarn in the Massif Central
mountain range and soaring into the record books.
"The height of the supports, the length of the work,
the number of pylons, it's an exceptional feat,"
crowed Jean-Frans Coste, head of the state's expert
control team, ahead of the bridge's inauguration .
The road is spectacular 270m above ground, along
2.46km.
The structure is 23m taller than the Eiffel Tower -
reaching 343m at its highest point.
Major motorway
Designed by Foster and financed by the French
construction group Eiffage, the soaring steel bridge
has already drawn praise from hundreds of thousands
of tourists.
Completing a major new motorway link from Paris to
the Mediterranean it removes a notorious bottleneck
through the town of Millau below.
Its seven slender pillars rise like giant needles
from the valley bed - one of them standing 245m, the
tallest in the world.
The Millau bridge was assembled using highly
innovative construction techniques.
From the north and south sides of the valley, the
metal sections of the bridge were assembled, lifted
slightly and then carefully slid into place on each
of seven supporting pillars.
The operation was repeated 18 times to bring the two
halves of the deck together.
The total metal structure weighs approximately 36
000 tonnes -- around one quarter of the weight of a
similar bridge built with concrete and conventional
techniques. It was built in record time, with
construction launched in December 2001.
Eiffage shouldered the entire construction cost of
394 million euros (524 million dollars) and has been
granted a concession to operate the bridge for 75
years.
Motorists will be charged ?4.6 for the trip across
the bridge, rising to ?6.5 in the summer months,
while heavy vehicles are to be charged ?19.
When he laid the first stone, communist transport
minister at the time Jean-Claude Gayssot called it
"the most beautiful and the biggest bridge in the
world". |
