Nuevo puente Champlain sobre el río San Lorenzo en Montreal. Diseño de las estructuras auxiliares para la construcción del puente atirantado

This article summarizes the design of the temporary structures used for the construction of the New Champlan Bridge in Montreal (Canadá). The complexity of the structure of the cable-stayed bridge, with a total width of 60 m and a strong asymmetry in elevation and in cross section, has been a real challenge for the design of the temporary works and assembly operations. It is explained in detail the singularity of the assembly and bolting operation of the Main Span segments, comprised of three composite box girders joined together by transverse girders.
