The Gustave-Flaubert lift bridge
This work of civil engineering avoids any impression of mass. The eye is drawn to the purity of its
strong lines and its sense of elegance. Yet the Gustave-Flaubert lift bridge in Rouen (Seine-Maritime),
which was built between 2004 and 2007 by Eiffage Travaux Publics and Eiffage Construction
Métallique, stands 86 metres high and is 120 metres long.
Designed to allow tall ships to pass through to the Normandy capital during the Armada that takes places there once every four years, and carry an estimated 50,000 vehicles per day, it has two metal decks 17 metres wide and 4.5 metres high, each weighing 1,350 tons. To raise the decks 55 metres in the air, eight winches connected to 64 pulleys using five kilometres of lifting cables, and 450 counterweights are set in motion.
