The Pont Caquot is a road bridge that leads today's D 1201 between the places Cruseilles and Allonzier-la-Caille in the French department of Haute-Savoie over the deeply cut river Les Usses .
history
It was built between 1925 and 1928 right next to the Pont de la Caille suspension bridge, which opened in 1839 . It was originally intended for a tram between Geneva and Annecy , but it was never realized. So it was soon able to take over the road traffic that had been running over the suspension bridge until then, which increased steadily on the then connecting road between Geneva via Annecy, Aix-les-Bains and Chambéry to Grenoble . After the A 41 motorway from Geneva to Grenoble was opened in 2007 and the former RN 201 was therefore downgraded to a departmental road, it only serves regional traffic.
description
The Pont Caquot is an arch bridge with an arch made of unreinforced concrete , on which the deck is elevated. At that time, the arch, created according to the plans of the engineer Albert Caquot , was the largest concrete arch that was built without reinforcing steel . At the same time, the bridge was the second tallest bridge in the world after the Pont Sidi M'Cid suspension bridge in Constantine (Algeria) and the neighboring Pont de la Caille.
The roadway of the 232 m long bridge is 147 m above the river. The arch has a wingspan of 137.5 m and an arrow height of 26.5 m.
Instead of a conventional falsework for concreting the arch, Caquot had ropes stretched between temporary steel masts on both sides of the valley, to which an arch made of wooden lattice girders was hung, which took over the function of the falsework.
