asimplemind Posted June 21, 2006 Report Posted June 21, 2006 "Having to replace a rope bridge destroyed by a rock fall over the Traversinertobel, in Switzerland, engineer Jürg Conzett and his associate Rolf Bachofner could only find two points where there would be no risk of rock falls. But one was too high and the other too low. Their solution is a suspended straicase-bridge that spans a distance of 56 metres." Já tínhamos visto uma ponte magnífica na súiça e neste momento podemos ver uma ponte-escada também na suíça. imagens: mais imagens: http://www.we-make-money-not-art.com/archives/008450.php Quote
