Client: SIPIT s.r.l.

Length of each viaduct: 376 m

Structural works value: 11.370.776,00 €

Design period: 2000÷2003

 

The work consists of two viaducts with a length of approximately 376 m and a total width of 18 m each made of a composite steel and concrete structure

The viaducts deck is made up of two steel beams with a variable cross section and static scheme of eighth spans continuous beam, completed by a upper r.c. slab with them collaborating.

Foundations and vertical structures are in reinforced concrete: single standing piers for each beam on footings with 120 cm diameter piles, and abutment piers constituted by diaphragms.

In addition, have been designed some box-shaped underpasses inside of the road embankment and the temporary works (sheet piling and r.c. diaphragms) needed for the realization of the excavations for the piers foundations near the surrounding road network that has not been interrupted during construction.
