The rehabilitation carried out in 2003 involved local repair of areas with signs of reinforcement corrosion, crack sealing, rehabilitation and replacement of bearings, reinforcement with carbon fibre laminates and corrosion protection with a thick, flexible coating. In 2023 and 2024, the seismic reinforcement of the viaduct was executed, involving the reinforcement of the main pilasters and the longitudinal connection between the decks of the central arch structures and viaducts.<\/p>\n","protected":false},"author":10,"featured_media":1244,"template":"","categoria-de--projet":[39,36],"class_list":["post-1217","projeto","type-projeto","status-publish","has-post-thumbnail","hentry","categoria-de--projet-road-bridges","categoria-de--projet-bridges-and-viaducts"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Duarte Pacheco Viaduct - A2P<\/title>\n<meta name=\"description\" content=\"Duarte Pacheco Viaduct was built in 1944 and was rehabilitated in 2003.
