APRES CEX D'OLERON ET DE NOIRMOUTIER, UN VIADC DE 957M DE LONG EST EN COURS DE CONSTRUCTION ENTRE LA TREMBLADE ET MARENNES EN CHARENTE-MARITIME

Details are given of a toll viaduct being built over the river La Seudre in the Department of Charente-Maritime. The structure, which should be opened to traffic at the end of the 1972 tourist season, is 957M long with access roads 3.5KM and 1.6KM long. The prefabricated curved deck consists of a tubular girder of trapezoidal shape which supports two cantilevers. The segments are transported on a truck running on rails and positioned by means of a launching beam. They are glued togehter and held with prestressing cables. The structure rests on 12 piers four of which are on footings, and eight on piles. The pavements of the access roads consist of a 20CM sand-bitumen layers, 8CM bituminous layer and 4CM asphaltic concrete layer. Observations are made on framework for the segments and on the difficulties arising from variations in height. Mention is made of a study conducted to accelerate setting and speed up handling. Costs are quoted.
