Description

The bridges over the N-II motorway are two identical curved composite structures formed in white concrete and weathering steel.

The main features are: composite piers for technical as well as aesthetic reasons; parapets and fascias made out of weathering steel; the special joints used to connect their precast concrete deck  planks so to improve the torsional behavior; and finally, the use of abutment piers and flexible abutments.

At the piers, concrete bottom slabs assure the double composite action of the superstructure.
