Description: The viaduct constructed between 2007 and 2009. The
deck, 200 meters long by 20,1 meters wide, is a mixed steel/reinforced
concrete structure. The steel framing is formed by a pair of longitudinal
box girders having a height just above one meter by two meters in width,
spaced out at 8 meter centres. The longitudinal box girders are connected
between each other and stiffened with “T” sections spaced out
at circa 4 meter centres. The box girders also form a surface for supporting
the pre-cast deck elements necessary for casting the reinforced concrete
deck. The arch, which develops overa length of approximately 170 meters,
is formed from a steel box girder of varying height with continuità
from the abutment, where the height is greater than 5 meters and the mean
width circa 2,6 meters, up to the arch ridge, where the box flattens out
and becomes 1 meter high by 10 meters wide.
Total tonnage: 2000 t
