The conclusion of the deep multi-criteria analysis
carried out after the bridge-type and constructionmethod studies was that the most appropriate
solution for this crossing was a viaduct with a global
length of almost 1000 m and a main span consisting of
a large 384-m span open-spandrel deck-arch, erected
using the cantilever method with the help of
temporary towers.
