The Mallau Bridge - Poetry In The Skies


I was getting ready to write something about our failing public education system when I caught a program called Extreme Engineering on the Discovery Channel. My mood went from disgust and anxiety over the state of our education system to admiration and excitement over man's accomplishments over nature.

A case in point is the amazing Mallau Viaduct a bridge over the river Tarn in the Massif Central Mountain range which opened on December 17, 2004. This marvel of the 21st century forms the final link in the A75 highway from Paris to Barcelona. It is 2.4 km long and stands 270 meters above the river at its highest point.
French and Spanish technicians and engineers were involved in the building of the bridge. The architect in charge of design was Norman Foster from England. His goal was to create an image of delicate transparency the "delicacy of a butterfly". If these pictures do it any justice he accomplished what he set out to do.

An amazing fact (go to www.roadtraffic-technology.com) is that construction began in October 2001! Think about it. Three years to construct a bridge of this magnitude? Unbelievable.

No cranes were used to hoist sections of the deck because of the 900 m height above the valley floor (at its tallest point). Instead new engineering techniques were used. The seven graceful towers were built first with steel reinforced concrete and then the road way (pre-constructed of high-grade steel instead of concrete in 2,000 pieces at the factory) was put together starting at both ends of the valley until "it met at the center with precision" thanks to GPS alignement, 60 cm at a time.

There is an 18-lane toll station that accommodates technical and administrative services as well and the trip across the bridge costs 5.60 dollars. What a bargain for a shorter and easier drive from Paris to the Mediterranean while experiencing the results of man's daring, technological ingenuity and can-d0 attitude.

The bridge cost was $524 million dollars (all private funds) and 500 men worked permanently at the site.

"A work of man must fuse with nature. The pillars had to look almost organic, like they had grown from the earth" (Norman Foster).

This is what happens when nations (France and Britain in this case) cooperate to achieve a common goal that advances the interests of the individual and of the nation. I can't help and compare this feat to its antithesis. The utter destructiveness and nihilistic results of the Jihadist-terrorists from the Middle East.

Maybe the West should send the people of the Middle East DVDs from the Discovery Channel to show them what the mind of man can create when he seeks to live his life by reason and achievement rather than live his life by death and destruction.

Wow! That is the most beautiful bridge I have ever seen, and I live near quite a beauty, if I don't say so myself, The Golden Gate Bridge. Thanks for sharing that one!

Breathtakingly beautiful. A work of art joining two magnificent cities. I hope to see and cross it one day.

I just saw it on national geographic channel as i attend a patient at our local hospital here in Cebu, it is so amazing that such megastructure can really be done, maybe someday i like to go there as my second most dream of seeing aside from the Grand Canyon which has a bridge open this year.
