The “Rio Grestales” flyover, classified as first category bridge, is composed by a single carriageway and it will be made in steel-concrete composite materials and characterized by a simply supported static scheme. The span is 30 m in length. The deck has a total width of 11.50 m with variable slope of the cross section. Part of the bridge is in curve with radius R=45 m from SP1 to ch.0+262.085 and part in clothoid.
The “Rio Melchiore” flyover, classified as first category bridge, is composed by a single carriageway and it will be made in steel-concrete composite materials and characterized by a simply supported static scheme. The span is 30 m in length. The deck has a total width of 10.95 m with constant slope of the cross section (7%). The bridge is totally in curve with radius R= 54 m.
The “Bitti-Sologo” flyover, classified as first
category bridge, is composed by a single carriageway and it will be made in
steel-concrete composite materials and characterized by a simply supported static
scheme. The span is 55 m
in length and the deck has a total width of 10.50 m. The cross section
is double slope type (2.5% of slope).
