The Sado Bridge and its access viaduct was a design and build tender with an extremely short construction period. The east structure, nearly 1800m long, was built in 6 months and the entire construction completed in just one year.<\/p>\n
Each of the two parallel bridge decks is a three span box girder with a total length of 302m. With a total length of 1452m, each of the two parallel access viaducts is made of three continuous structures each 484m long.<\/p>\n
The prestressed concrete decks were cast \u201cin situ\u201d. The bridge was built using the balanced cantilever method in 5m segments and the access viaduct ones using the span-by-span method with three under-slung self-launching girders.<\/p>\n
The foundations are indirect with 2.50m diameter piles for the bridge and 1.50m diameter piles for the viaducts, all with an average depth of 50m. The pile\/pier concept was used, this meaning that the piers are the natural extension of the piles.<\/p>\n
The construction was completed in February of 1999.<\/p>\n","protected":false},"featured_media":0,"template":"","categories":[],"tags":[],"class_list":["post-5233","projectos","type-projectos","status-publish","hentry"],"acf":{"enquadramento":"r2","imagem_hp_destaque":{"ID":3802,"id":3802,"title":"P220_Projeto_855x320","filename":"P220_Projeto_855x320.jpg","filesize":61239,"url":"https:\/\/www.arito.com.pt\/wp-content\/uploads\/2021\/06\/P220_Projeto_855x320.jpg","link":"https:\/\/www.arito.com.pt\/en\/projectos\/ponte-sobre-o-rio-sado\/p220_projeto_855x320\/","alt":"","author":"12","description":"","caption":"","name":"p220_projeto_855x320","status":"inherit","uploaded_to":3801,"date":"2021-06-27
