Abstract:
The Trapagaran viaduct was divided into three parts: main viaduct, access viaduct and transition area. The main viaduct is 670 m long with 125 m spans. It is formed by a 35.60 m wide, 5.90 m deep prestressed concrete box cross section. The access viaduct is formed by four separate structures with spans reaching 86 m. Each of the decks is made up of a composite 3.50 m deep box girder. The four branches converge in the transition area displaying complex geometry. The transition area is a prestressed concrete structure of approximately 60 m in span executed on falsework.
