des usagers au quotidien. Le projet comprend l\u2019\u00e9largissement des chauss\u00e9es sur l\u2019ensemble de la section et plusieurs am\u00e9nagements associ\u00e9s (cr\u00e9ation de bassins de recueil et de traitement des eaux, installation de merlons et d\u2019\u00e9crans antibruit, r\u00e9alisation de bretelles d\u2019acc\u00e8s et de giratoires\u2026). La principale difficult\u00e9 tient toutefois \u00e0 l\u2019\u00e9largissement du pont de Chateaubriand, un ouvrage \u00e0 arc de 424 m de long qui surplombe le fleuve Rance.<\/p><p>Ma\u00eetre d\u2019\u0153uvre du projet, Artelia apporte toute son attention \u00e0 l\u2019\u00e9largissement de cet ouvrage d\u2019art qui constitue l\u2019\u00e9l\u00e9ment le plus complexe et technique, aussi bien du point de vue des \u00e9tudes de conception que de sa r\u00e9alisation. Cet ouvrage remarquable, mis en service en 1991, a marqu\u00e9 l\u2019histoire contemporaine des ponts en arc, avec son importante ouverture de 261 m. L\u2019\u00e9largissement de son tablier constituera une op\u00e9ration in\u00e9dite pour ce type d\u2019ouvrage en France. \u00c0 cela s\u2019ajoutent des enjeux environnementaux, car cette infrastructure traverse un site exceptionnel, l\u2019estuaire de la Rance, inscrit au r\u00e9seau europ\u00e9en Natura 2000. Un soin particulier sera \u00e9galement port\u00e9 \u00e0 la limitation des perturbations de trafic et aux nuisances qu\u2019occasionneront les travaux, dont le d\u00e9marrage est programm\u00e9 pour 2025.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-abfcc45 elementor-widget elementor-widget-button\" data-id=\"abfcc45\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/www.arteliagroup.com\/fr\/contact\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Contactez-nous<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-3b10db68 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"3b10db68\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-37b9b300\" data-id=\"37b9b300\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-2e066ca3 elementor-widget elementor-widget-spacer\" data-id=\"2e066ca3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Doublement des voies et du pont de Chateaubriand<\/p>\n","protected":false},"featured_media":11274,"template":"","country":[263],"market":[247],"challenge":[260],"class_list":["post-11269","project","type-project","status-publish","has-post-thumbnail","hentry","country-france-fr","market-mobilite","challenge-mobilite-multimodale"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
