Replacement of the Suspension of the Aquitaine Bridge in Bordeaux
The Aquitaine bridge across the Garonne was open to traffic in 1967. Its central span is 393.75 m long, and its total length is 1,767 m. The first indications of corrosion in the main cables were observed in 1979. In 1998, a detailed inspection showed that 2 % of the wires were broken. The article describes the various investigations conducted (measurement of tension, evaluation of safety coefficient and fatigue risks), the high level monitoring applied (by acoustic monitoring), the choice of the adopted solution among other alternatives in the context of widening the deck and maintaining the traffic during repair, and the anti-corrosion protection of the new cables.
