Comme le pont Anne-de-Bretagne, dont le chantier a d\u00e9marr\u00e9 en janvier, le pont des Trois-Continents qui relie l\u2019\u00eele de Nantes \u00e0 Rez\u00e9 (Loire-Atlantique) va se transformer pour recevoir, fin 2027, les futures lignes 6 et 7 du tramway, ainsi que la ligne 8 du busway. Les travaux d\u2019un montant de 10,8 M\u20ac viennent de d\u00e9marrer sous la ma\u00eetrise d\u2019ouvrage d\u00e9l\u00e9gu\u00e9e de la Semitan pour le compte de Nantes M\u00e9tropole et la ma\u00eetrise d\u2019\u0153uvre du groupement Egis et Richez_Associ\u00e9s. Ils sont r\u00e9alis\u00e9s par Bouygues Travaux publics R\u00e9gions France avec ses directions m\u00e9tiers VSL France et M\u00e9tal & Bois.<\/p>\n
Elargissement de 2,50 m<\/p>\n
Mis en service en 1995, ce pont \u00e0 caissons mesure 273 m de long pour 22 m de large. Afin de cr\u00e9er un axe s\u00e9curis\u00e9 pour les mobilit\u00e9s douces, l\u2019op\u00e9ration de transformation pr\u00e9voit un \u00e9largissement de 2,50 m c\u00f4t\u00e9 aval gr\u00e2ce \u00e0 une structure m\u00e9tallique attel\u00e9e au tablier. L\u2019ouvrage va \u00e9galement subir un renforcement structurel important par pr\u00e9contrainte et via l\u2019utilisation de composites carbone pour solidifier certaines zones du tablier dont l\u2019\u00e9paisseur varie de 3 \u00e0 7 m. Les appareils d\u2019appui seront aussi remplac\u00e9s. Un dispositif a \u00e9t\u00e9 imagin\u00e9 pour permettre de maintenir la circulation (automobiles, v\u00e9los et pi\u00e9tons) d\u00e8s les premiers travaux. Temps fort du chantier, l\u2019\u00e9largissement du tablier apr\u00e8s d\u00e9molition d\u2019une petite partie de la structure d\u2019origine interviendra \u00e0 partir du printemps 2026.<\/p>\n","protected":false},"excerpt":{"rendered":"Comme le pont Anne-de-Bretagne, dont le chantier a d\u00e9marr\u00e9 en janvier, le pont des Trois-Continents qui relie l\u2019\u00eele…\n","protected":false},"author":2,"featured_media":580824,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2818],"tags":[1111,11,1777,674,1011,27,5495,3047,1137,766,12,2636,25,4109,800,7333],"class_list":{"0":"post-580823","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nantes","8":"tag-actu","9":"tag-actualites","10":"tag-eu","11":"tag-europe","12":"tag-fr","13":"tag-france","14":"tag-infrastructures","15":"tag-loire-atlantique","16":"tag-mobilite","17":"tag-nantes","18":"tag-news","19":"tag-pays-de-la-loire","20":"tag-republique-francaise","21":"tag-tramway","22":"tag-transports","23":"tag-vie-du-btp"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@fr\/115669358577860419","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts\/580823","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/comments?post=580823"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts\/580823\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/media\/580824"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/media?parent=580823"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/categories?post=580823"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/tags?post=580823"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
